--- name: "xxxterm" section: "1" platform: "linux" package: "xxxterm" version: "1:1.11.3-1" release: "Debian 7 (Wheezy)" platforms: ["linux"] url: "https://new.carta.tech/xxxterm" --- # xxxterm(1) lightweight web browser ## NAME **xxxterm** – lightweight web browser ## SYNOPSIS **xxxterm** \[**-nSTtV**\] \[**-f** *file*\] \[**-s** *session\_name*\] \[*url* *...*\] ## DESCRIPTION **xxxterm** is a minimalistic web browser that tries to stay out of the way so that valuable screen real estate can be used for much more important stuff. It has sane defaults and does not require one to learn a language to do any configuration. It was written by hackers for hackers and it strives to be small, compact, and fast. **xxxterm** is very simple in its use. Most actions are initiated via key or mouse bindings. Key bindings are based on those of the [vi(1)](/vi/1.md) text editor, giving web browsing a similar feel to navigating a text document. The KEY BINDINGS section below documents the various defaults and possible customizations. The options are as follows: - **-f** *file* Specify an alternative configuration file. - **-n** Open a new tab in a running **xxxterm** for each specified URL. This option requires **enable\_socket** to be enabled. - **-e** *command* Execute arbitrary command (see the COMMAND MODE section below) in a running **xxxterm** instance. This option requires **enable\_socket** to be enabled. Example run: xxxterm -e "tabnew openbsd.org"; xxxterm -e tabclose; xxxterm -e wq. - **-S** Disable the toolbar. - **-s** *session\_name* Open session that was saved with ":session save" command. - **-T** Disable visualization of tabs. - **-t** Disable tabs. - **-V** Display version and exit. ## FAST STARTUP The following notation is used throughout this page: - **C-** Control - **S-** Shift - **M1-** Meta 1 (sometimes marked Alt) - **M2-** Meta 2 - **M3-** Meta 3 - **M4-** Meta 4 (sometimes marked Windows) - **M5-** Meta 2 - **MB1** Mouse button 1 To browse to a specific address, either use the mouse to click on the address bar or press **F6** to shift the keyboard focus to the address bar. The address is then entered manually. The mouse can be used to navigate the page in the traditional manner, or the keyboard can be used instead. For example, **PageUp** and **PageDown** will scroll up and down the page. To follow a link, either click on it or use the **f** key and have **xxxterm** assign numbers to each link on the page; entering that number on the keyboard will prompt **xxxterm** to follow the link. ## KEY BINDINGS **xxxterm** provides many actions accessed via key or mouse bindings. Most can be reprogrammed using a **keybinding** entry in the configuration file. Each keyboard shortcut requires exactly one entry in the configuration file. A shortcut can have multiple entries in the configuration file. The format of the keybinding entry is as follows: keybinding = action,(!)keystroke(s) For example, "keybinding = tabnew,C-t" where **tabnew** is the action and **C-t** are the keystrokes. GTK has some default keybindings for manipulating text inside input fields, such as the URI or search entry widget, for example **C-w** deletes a word. To override these defaults prefix your key with an exclamation mark, like this: "keybinding = tabclose,!C-w". The **clearall** key word is special and is meant to reset the key binding list to the GTK+ and WebKit defaults. This keyword should be the first **keybinding** entry in the configuration file. Shift should be used sparingly since it gets in the way of non-USA keyboards. See the accompanying configuration file for examples. The various bindings are documented below. The relevant keybinding action is given afterwards, in parentheses. ### Command mode These commands are used to focus or unfocus input on the default input of a web page. - **ESC** Go to command mode; unfocus current entry on web page. (**command\_mode**) - **i** Go to insert mode; focus on default entry on web page. (**insert\_mode**) ### Search Commands These commands are used to search for text strings within a web page. - **/** Start a search (**search**) - **?** Start a backwards search (**searchb**) - **n** Next item matching search (**searchnext**) - **N** Previous item matching search (**searchprev**) ### Focus Commands These commands are used to shift the focus of **xxxterm** from one area to another. - **F6** Focus on address bar (**focusaddress**) - **F7** Focus on search entry (**focussearch**) ### Command Aliases These commands allow the user to map specific actions to specific keys. It can be useful when the **-S** option is used. - **F1** Alias for ":help" - **F2** Alias for ":proxy toggle" - **F4** Alias for ":toplevel toggle" - **F9** Alias for ":open" (**promptopen**) - **F10** Alias for ":open current-uri" (**promptopencurrent**) - **F11** Alias for ":tabnew" (**prompttabnew**) - **F12** Alias for ":tabnew current-uri" (**prompttabnewcurrent**) ### Navigation Commands These commands allow the user to navigate web pages and, to some extent, control the browser. - **F5,** **C-r,** **C-l** Reload page (**reload**) - **Backspace,** **M-Left** Previous page (**goback**) - **S-BackSpace,** **M-Right** Forward page (**goforward**) - **j,** **Down** Next line on page (**scrolldown**) - **k,** **Up** Previous line on page (**scrollup**) - **G,** **End** Bottom of page (**scrollbottom**) - **gg,** **Home** Top of page (**scrolltop**) - **Space,** **C-f,** **PageDown** Page down (**scrollpagedown**) - **C-b,** **PageUp** Page up (**scrollpageup**) - **l,** **Right** Page right (**scrollright**) - **h,** **Left** Page left (**scrollleft**) - **$** Page far right (**scrollfarright**) - **0** Page far left (**scrollfarleft**) - **M-f** Favorites (**fav**) - **M-j** Cookie jar (**cookiejar**) - **M-d** Download manager (**dl**) - **C-p** Print page (**print**) - **M-h** Global history (**history**) - **C-j** Toggle Java Script enabled for FQDN (**js**) - **C-s** Toggle source view (**togglesrc**) - **M-c** Toggle cookie enabled for FQDN (**cookie**) - **M-p** Toggle plugins enabled for FQDN (**plugin**) ### Tab Manipulation **xxxterm** supports tabbed browsing. That is, web pages may be opened in separate tabs, allowing the user to quickly move from one page to another, and back. These commands then are used to create, destroy, and move between tabs. - **C-MB1** Open new tab with the clicked link - **C-t** Create new tab with focus in URL entry (**tabnew**) - **C-T** Create new tab with focus in URL entry as the last tab in the browser (**999tabnew**) - **C-w** Destroy current tab (**tabclose**) - **U** Undo close tab (**tabundoclose**) - **C-Left,** **C-PageUp** Go to the previous tab (**tabprevious**) - **C-Right,** **C-PageDown** Go to the next tab (**tabnext**) - **C-\[1..9\]** Jump to page *N* (**tabnext** **\[1..9\]**) - **C-\<** Jump to first page (**tabfirst**) - **C-\>** Jump to last page (**tablast**) - **C-minus** Zoom out by 4% (**focusout**) - **C-plus,** **C-equal** Zoom in by 4% (**focusin**) - **C-0** Set zoom level to 100% (**focusreset**) ### Yanking and pasting These commands copy and paste text to and from the clipboard. - **p** Paste the contents of the clipboard into the address bar (**pasteuricur**) - **P** Paste the contents of the clipboard into a new tab (**pasteurinew**) - **y** Yank the current URL into the clipboard (**yankuri**) ### Hyperlink Following This allows the user to follow hyperlinks without using a mouse. Enter the corresponding number to follow the link. Alternatively one can type the name of the link and when there are no more possibilities **xxxterm** will follow the link. - **f,** **'.'** Highlight all links and prefix them with a number. (**hinting**) - **F,** **','** Highlight all links and prefix them with a number but open in a new tab. (**hinting\_newtab**) ### Exiting Commands to exit the browser. - **C-q** Quit (**quitall**) ### Low-Contrast Color Scheme These commands toggle the page style between the default CSS and a low-contrast color scheme with light grey text on a dark grey background. - **s** Toggle the current tab's style. (**userstyle**) - **S** Toggle the global page style mode. Will also affect new tabs. (**userstyle\_global**) ### Insert-mode commands The following commands are only available when editing an input-field - **C-i** Edit the contents of the currently active input-element in an external editor. (**editelement**) ## COMMAND MODE Command mode works in a similar fashion to the [vi(1)](/vi/1.md) editor; it is entered by typing a colon and exited by typing Esc. The commands and their descriptions are listed below. - **about**, **version** Show the "About" page. - **buffers**, **ls**, **tabs** Displays the currently open tabs and lets the user switch tab by typing the tab number or using the mouse. - **ca** Display CA certificates. - **cert**, **cert** **show** Download and display certificates of domain on tab. - **cert** **save** Save certificate into a local store. The next time the site is visited it is compared against the store. If the certificate matches, the address bar will be blue; if it doesn't the bar will be red. - **cookie** The **cookie** command is used to manipulate the cookie whitelist. Used by itself it expands to **cookie** **show** **all**. - **cookiejar** Show cookie jar contents. - **cookie** **purge** Remove all cookies from the cookie jar. - **cookie** **save,** **cookie** **save** **fqdn** Save the current fully qualified domain name (FQDN) to the persistent whitelist. For example, the www.peereboom.us domain would result in saving .www.peereboom.us. - **cookie** **save** **domain** Save the top level domain name to the persistent whitelist. For example, the www.peereboom.us domain would result in saving .peereboom.us.

For example, the www.peereboom.us domain would result in saving .www.peereboom.us. - **plugin** **save** **domain** Saves the top level domain name to the persistent whitelist. For example, the www.peereboom.us domain would result in saving .peereboom.us. This action enables plugins if they are currently disabled for this entry. - **plugin** **show** **all** Shows all persistent and session entries in the plugin whitelist. - **plugin** **show** **persistent** Shows all persistent entries in the plugin whitelist. - **plugin** **show** **session** Shows all session entries in the plugin whitelist. - **plugin** **toggle,** **plugin** **toggle** **fqdn** Toggle plugin execution for the current FQDN. - **plugin** **toggle** **domain** Toggle plugin execution for the current top level domain. - **print** Print page. - **proxy** The **proxy** command is used to manipulate the currently set proxy. Used by itself it expands to **proxy** **show**. - **proxy** **show** Displays the current **http\_proxy** setting. - **proxy** **toggle** Enables or disables the proxy for **xxxterm**. Note that **http\_proxy** must be set before it can be toggled. - **qa**, **qall**, **quitall** Quit **xxxterm**. - **quit**, **q** Close current tab and quit **xxxterm** if it is the last tab. - **restart** Restart **xxxterm** and reload all current tabs. - **run\_script** **\[path\_to\_script\]** Runs the script path\_to\_script with the current uri as the argument. If path\_to\_script is not provided, the value of default\_script is used instead. - **script** **\[filename\]** Run an external JavaScript script file in the current tab context. - **session**, **session** **show** Display the current session name. By default the session name is main\_session. To create a new session use the **session** **save** command. A session is defined as the lifetime of the browser application. - **session** **delete** **\** Delete session session\_name from persistent storage. If session\_name is the current session then the session will revert to main\_session. - **session** **open** **\** Open session\_name and close all currently open tabs. Going forward this session is named session\_name. - **session** **save** **\** Save current tabs to session\_name session. This will close the current session and going forward this session is named session\_name. - **set** The set command is used to inspect, clear or change runtime options. There are 3 methods to use **:set**. When used by itself as **:set** the command displays all options as currently set. To set a value use **:set** **option=value**. For example, **:set** **http\_proxy=http://127.0.0.1:8080**. To clear a value use **:set** **option=**. For example, **:set** **http\_proxy=**. Note, not all options can be set at runtime. - **stats** Show blocked cookie statistics.

This is to enable/disable short lived full site functionality without permanently adding the top level domain to the persistent whitelist. - **urlhide**, **urlh** Hide url entry and tool bar. - **urlshow**, **urls** Show url entry and tool bar. - **userstyle** Toggle between normal and low contrast mode. - **w** Save open tabs to current session. The tabs will be restored next time the session is opened. See the session command for additional details. - **wq** Save open tabs and quit. The tabs will be restored next time **xxxterm** the session is opened. See the session command for additional details. ## BUFFER COMMANDS In addition to shortcuts and commands **xxxterm** provides buffer commands. Buffer commands are short, multi character vi-like commands, often requiring an argument. Partial buffer commands are displayed in the buffer command statusbar element (see **statusbar\_elems**). Pressing Esc or switching to another tab cancels a partially entered buffer command. In the following list **arg** denotes the argument a buffer command accepts. Buffer commands are defined as extended regular experssions. Note that if a character is used as a shortcut it will not be interpreted as the beginning of a buffer command. This is the case with **0**. - **gg** go to the top of the page - **gG** go to the bottom of the page - **\[0-9\]+%** go to the **arg** percent of the page - **zz** go to 50% of the page - **\[0-9\]\*gu** go **arg** levels up. If **arg** is missing, 1 is assumed. Going a level up means going to a URI obtained from the current one by removing the last slash ('/') character and everything that follows it - **gU** go to the root level, i.e. going up as many levels as possible. - **gh** open the home page in the current tab - **m\[a-zA-Z0-9\]** set a mark denoted by **arg** at the current page position. These marks behave like those in vi or less. - **\['\]\[a-zA-Z0-9\]** go to the position where mark **arg** was set - **M\[a-zA-Z0-9\]** set the current uri as quickmark **arg** - **go\[a-zA-Z0-9\]** open the uri marked as quickmark **arg** in the current tab - **gn\[a-zA-Z0-9\]** open the uri marked as quickmark **arg** in a new tab - **\[0-9\]+t** activate tab number - **g0** go to first tab - **g$** go to last tab - **\[0-9\]\*gt** go to the **arg** next tab - **\[0-9\]\*gT** go to the **arg** previous tab **arg** - **ZZ** quit **xxxterm** - **ZR** restart **xxxterm** - **zi** zoom in by 4% - **zo** zoom out by 4% - **z0** set zoom level to 100% - **\[0-9\]+Z** set zoom level to **arg** % ## QUICKMARKS Quickmarks are like bookmarks, except they are refered to by a single character (a letter or a digit), instead of a longer name. See the **M\[a-zA-Z0-9\]**, **go\[a-zA-Z0-9\]** and **gn\[a-zA-Z0-9\]** buffer commands for usage. Quickmarks are stored in *~/.xxxterm/quickmarks* and are saved automatically after each **M\[a-zA-Z0-9\]** buffer command. ## ABOUT SCREENS The about screens are internally generated web pages by **xxxterm** for user interaction. These are entered in the address bar and the format is **about:screen** where screen is the desired screen to display. For example about:favorites. Any about screen can be used as the home page as specified by **home** in the configuration file. - **about** show the about screen - **blank** show a blank screen - **cookiewl** show the cookie whitelist screen - **cookiejar** show the cookiejar screen - **downloads** show the downloads screen - **favorites** show the favorites screen - **help** show the help web page - **history** show the history screen - **jswl** show the Java Script whitelist screen - **set** show the settings screen - **stats** show the statistics screen ## WHITELISTS This section describes advanced usage settings. Most users should use **browser\_mode** instead to setup **xxxterm** and skip over this section. **xxxterm** has a number of whitelists to control blocking cookies and Java Script execution for FQDNs or domains. When properly enabled these whitelists require either the FQDN or top level domain to exist in the whitelists in order to allow cookies to be stored or Java Script to execute. Both Java Script and cookies have two whitelists associated with them. The whitelists are called session and persistent. Items in the session whitelists are only allowed for the lifetime of the **xxxterm** instance. Items in the persistent whitelists are stored on disk and are restored upon restarting. Setting up the whitelists is a little tricky due to intricacies of WebKit. In fact the semantics are different for cookies and Java Script. Cookie whitelist requires the following configuration to be set: - **cookies\_enabled** This is a WebKit setting and must be set to *1* (ENABLED) in order to be able to use a cookie whitelist. - **enable\_cookie\_whitelist** This needs to be set to *1* to enable the cookie whitelist functionality. - **cookie\_wl** These entries in the configuration file are the actual domains names in the cookie whitelist. Java Script whitelist requires the following configuration to be set: - **enable\_scripts** This is a WebKit setting and must be set to *0* (DISABLED) in order to be able to use a Java Script whitelist. - **enable\_js\_whitelist** This needs to be set to *1* to enable the Java Script whitelist functionality. - **js\_wl** These entries in the configuration file are the actual domains names in the Java Script whitelist. Plugin whitelist requires the following configuration to be set: - **enable\_plugins** This is a WebKit setting and must be set to *1* (ENABLED) in order to be able to use a plugin whitelist. - **enable\_plugin\_whitelist** This needs to be set to *1* to enable the plugin whitelist functionality. - **pl\_wl** These entries in the configuration file are the actual domains names in the plugin whitelist. See the *FILES* section for additional configuration file entries and details that alter runtime behavior. ## FILES - *~/.xxxterm.conf* **xxxterm** user specific settings. - *~/.xxxterm* **xxxterm** scratch directory. **xxxterm** tries to open the user specific file, *~/.xxxterm.conf*. If that file is unavailable, it then uses built-in defaults. The format of the file is keyword = setting. For example: ``` http_proxy = http://127.0.0.1:8080 ``` Enabling or disabling an option is done by using 1 or 0 respectively. The file supports the following keywords: - **alias** Defines an alias for a given URL, so that the URL is loaded when the alias is entered in the address bar. If the aliased URL includes a %s format specifier, then any argument given after the alias on the address bar is substituted. For example, if g,http://www.google.com/search?q=%s is defined as an alias, then the URL http://www.google.com/search?q=foo is loaded when navigating to "g foo". - **allow\_volatile\_cookies** If set cookies are stored in the session cache but will be discarded once **xxxterm** exits. Unfortunately enabling this does allow for some limited tracking on the web. - **append\_next** When set a new tab is appended after the current tab instead of being appended as the last tab. - **auto\_load\_images** If disabled, images will not be loaded automatically. - **autofocus\_onload** When set a tab that is loaded will attempt to autofocus the default input entry. This is only done for tabs that are currently visible. - **browser\_mode** The **xxxterm** browser has 3 default operating modes: *normal* (the default), *whitelist* and *kiosk*. In the *normal* mode the browser allows all cookies, plugins and Java Script as any other browser would. This means that all cookies are saved to persistent storage and that all Java Script and plugins run. On the other hand, using the *whitelist* mode enables whitelists. This requires the user to add all the required *cookie\_wl*, *js\_wl* and *pl\_wl* items. If a domain does not appear in the whitelists **xxxterm** disallows cookies, Java Script and plugin execution. In *kiosk* mode the browse works just like *normal* mode however the toolbar only has the backward, forward and home button. This setting must be the first entry in *~/.xxxterm.conf* because it sets advanced settings that can be overridden later in the file. See the default config file for more details. - **cmd\_font** Set the command prompt font. E.g. *cmd\_font* *=* *monospace* *normal* *9*. - **color\_visited\_uris** When enabled (the default) **xxxterm** will color visited links. This is done while the web page loads using JavaScript, rather than WebKit's (broken, see bug #51747) built-in facility for coloring visited links. The JavaScript approach is (probably) slower and is not consistent across tabs (unless the tabs are reloaded), but has the advantage of not leaking history data to web pages (see http://wtikay.com/docs/details.html). - **cookie\_policy** This field delineates the cookie policy. Possible values are: no3rdparty, reject 3rd party cookies. accept, accept all cookies. reject, reject all cookies. - **cookie\_wl** This is a cookie whitelist item. Use multiple times to add multiple entries. Valid entries are for example \*.moo.com and the equivalent .moo.com. A fully qualified host is also valid and is for example www.moo.com. - **cookies\_enabled** Enable cookies. - **ctrl\_click\_focus** Give focus in newly created tab instead of opening it in the background. - **default\_script** Path to the script used as the default value for the run\_script command. - **default\_zoom\_level** Set the default browsing zoom level. - **download\_dir** Locations where files are downloaded to. This directory must exist and **xxxterm** validates that during startup. - **download\_mode** Controls how downloads are handled. Possible values are: ``` start - automatically start download. ask - ask user for confirmation. add - add to downloadmanager, but do not start. ``` The default is "start". - **enable\_autoscroll** When enabled clicking MB3 will spawn the autoscroll ball, scrolling can then proceed by dragging the mouse away from the ball. - **enable\_cookie\_whitelist** When enabled all cookies must be in the whitelist or they are rejected. Additionally whitelisted cookies also enable HTML5 local storage for the domain. - **enable\_favicon\_entry** When enabled (the default) **xxxterm** displays the favicon of the web page at the URI entry. This setting affects both **normal** and **compact** tabs. - **enable\_favicon\_tabs** When enabled (disabled by default) **xxxterm** displays favicons at each tab. This setting only affects **compact** tabs. - **enable\_js\_whitelist** When enabled all domains must be in the js whitelist in order to run Java Script. NOTE: Make sure **enable\_scripts** is set to 0. - **enable\_plugin\_whitelist** When enabled all domains must be in the plugin whitelist in order to run plugins. NOTE: Make sure **enable\_plugins** is set to 0. - **enable\_plugins** Enable external plugins such as Flash and Java. - **enable\_strict\_transport** Enable support for the Strict-Transport-Security HTTP-header. When enabled, sites that set this flag will only be visited via HTTPS. Default value is 1 - **enable\_scripts** Enable Java Script. - **enable\_socket** When enabled the first instance of **xxxterm** will create a socket in the *~/.xxxterm* directory. Using the -n url option on subsequent **xxxterm** invocations will cause the specified URL to be loaded in a new tab. Only a user with identical UID and GID can use this option. - **enable\_localstorage** Enable html5 Local Storage. - **enable\_spell\_checking** Enables spell checking. Preferred languages can be set using **spell\_check\_languages** option. - **encoding** Set the default encoding. E.g. *encoding* *=* *ISO-8859-1*. - **external\_editor** Set which editor to use for external editing. the string \ will be replaced by the current filename. E.g. *external\_editor* *=* *gvim* *-f* *\* Note! **xxxterm** relies on the editor *not* *forking* into the background. - **fancy\_bar** Enables a backward, forward, and stop button to the toolbar. Additionally if **search\_string** is set it'll enable an entry box for searches. - **guess\_search** When enabled **xxxterm** will try to guess if the string you entered, in the URI entry widget or the command widget, is term you want to search for using search\_string (see above). If the string does not contain a dot nor a slash, is not a path to a local file and does not resolves to an IP then it is assumed to be a search term. - **gui\_mode** To simplify configuring **xxxterm** allows you pick between two GUI modes: *classic* (the default) and *minimal*. In the *classic* mode the GUI looks similar to that of most mainstream browsers. While in *minimal* mode the GUI looks more vi-like. One can get a GUI between the two by tweaking the low-level GUI settings found under the advanced GUI setting section in the configuration file. - **history\_autosave** When enabled **xxxterm** will save all command and search history. Upon restarting **xxxterm** the saved command and search history will be restored. - **home** Homepage in URL format. - **http\_proxy** Proxy server in URL format. **xxxterm** overrides **http\_proxy** if it is specified as an environment variable. It must be noted that on older webkit versions one MUST use an IP address and not a FQDN. This works as expected with webkit 1.4.2. If one desires to use a socks proxy then an intermediary tool must be used. It has been reported that tsocks works with **xxxterm**. - **icon\_size** Permits icon sizes to be changed if **fancy\_bar** is enabled. Size 1 is small; 2 is normal; 3 through 6 are progressively larger. - **js\_wl** This is a Java Script whitelist item. See **cookie\_wl** for semantics and more details. - **max\_connections** The maximum number of connections that **xxxterm** can open at once. - **max\_host\_connections** The maximum number of connections that **xxxterm** can open at once to a given host. - **mime\_type** Sets an action for a specific or default MIME type. For example, to download and view a pdf using kpdf set *mime\_type* *=* *application/pdf,kpdf*. To set a default value use \*, for example, *mime\_type* *=* *video/\*,mplayer*. Note that the action is only passed the URL and not all applications are capable of dealing with a URL and therefore one might have to create a wrapper script to download the content first. Alternatively one can add the *@* in front of the MIME type to indicate "download first". For example, *mime\_type* *=* *@application/pdf,xpdf*. When *@* is use the file will be downloaded to the *download\_dir* before the MIME handler is called. - **oops\_font** Set the font used to display error messages. E.g. *oops\_font* *=* *monospace* *normal* *9*. - **pl\_wl** This is a plugin whitelist item. See **cookie\_wl** for semantics and more details. - **read\_only\_cookies** Mark cookies file read-only and discard all cookies once the session is terminated. - **refresh\_interval** Refresh interval while in the download manager. The default is 10. - **referer** Control how 'Referer' is handled in http-requests. ``` always - always send referer never - never send referer same-domain - only send referer if it's for the same domain ``` Any other value that is also a valid URL will use this custom value as referer. (E.g. you could set it to http://no-referer.com) The default value is "always" - **resource\_dir** Directory that contains various **xxxterm** resources such as icons. This is OS-specific and should be handled by the porter. - **save\_global\_history** If set the global history will be saved to *~/.xxxterm/history* when quitting and restored at startup. See the KEY BINDINGS section above for how the global history is accessed. Global history is not saved to disk by default. - **save\_rejected\_cookies** Saves rejected cookies in cookie format in {work\_dir}/rejected.txt. All cookies are saved and unlike a cookie jar they are never replaced. Make sure there is enough disk space to enable this feature. - **search\_string** Default search engine string. See the *xxxterm.conf* file for details. - **session\_autosave** Enable session auto-saving when changing state (e.g. adding or removing a tab). The session name is what is currently in use and is described in the **session** **save** and **session** **open** commands. - **session\_timeout** This value is the time that is added in seconds to a session cookie. - **show\_tabs** Enable or disable showing tabs. - **show\_url** Enable or disable showing the url and toolbar. - **show\_statusbar** Enable or disable showing the status bar. - **single\_instance** If set and **enable\_socket** is enabled only one **xxxterm** will be permitted to run. If there is a URL specified it will be opened in a new tab in the already running **xxxterm** session. - **spell\_check\_languages** The languages to be used for spell checking, separated by commas. For example, en\_US. - **ssl\_ca\_file** If set to a valid PEM file all server certificates will be validated against it. The URL bar will be colored green (or blue when saved ) when the certificate is trusted and yellow when untrusted. If **ssl\_ca\_file** is not set then the URL bar will color all HTTPS connections red. WebKit only supports a single PEM file. Many OS' or distributions have many PEM files. One can simply concatenate all separate files into one large one. E.g. **for** **i** **in** **\`ls\`;** **do** **cat** **$i** **\>\>** **cert.pem;** **done** and use the resulting cert.pem file as the input to **ssl\_ca\_file**. It is advisable to periodically recreate the cert.pem file. - **ssl\_strict\_certs** If this value is set connections to untrusted sites will be aborted. This value is only used if **ssl\_ca\_file** is set. - **statusbar\_elems** Define the components of the status bar. The possible components are: ``` | - separator P - page progress percent B - buffer command Z - page zoom level ``` The default is "BP". These components show nothing if there is nothing worth showing, like zoom amount 100%. - **statusbar\_font** Set the status bar font. E.g. *statusbar\_font* *=* *monospace* *normal* *9*. - **tab\_style** Set the tab style to either **normal** - the default gtk notebook tabs, or **compact** for an alternative. You can switch the tab style with the *tabnextstyle* command. - **tabbar\_font** Set the compact tab bar font. E.g. *tabbar\_font* *=* *monospace* *normal* *9*. - **url\_regex** This is the regular expression that is used to match what constitutes a valid URL when using *guess\_search*. - **user\_agent** Set to override the default **xxxterm** user-agent string. May be specified several times for switching between user-agents. - **userstyle\_global** When enabled new tabs will automatically be displayed in low contrast mode. - **window\_height** Set the default height of the browser window. - **window\_width** Set the default width of the browser window. - **window\_maximize** Maximize the browser window at startup. - **work\_dir** Set the work directory where all **xxxterm** scratch files are stored. Default is **~/.xxxterm**. - **xterm\_workaround** When enabled **xxxterm** will look additionally at CUT\_BUFFER0 if PRIMARY clipboard is empty. Additionally when the PRIMARY clipboard is cleared it will copy CUT\_BUFFER0 into the PRIMARY clipboard. Default is 0. ## HISTORY **xxxterm** was inspired by vimprobable2 and the bloat in other UNIX web browsers. ## AUTHORS **xxxterm** was written by Marco Peereboom ⟨marco@peereboom.us⟩, Stevan Andjelkovic ⟨stevan@student.chalmers.se⟩, Edd Barrett ⟨vext01@gmail.com⟩, Todd T.
