This is done via a configuration file. + +File location +------------- + +nxagent searches for the configuration file in the following order: +- in the location given by the '-keystrokefile' command line parameter +- in the location given by the NXAGENT_KEYSTROKEFILE environment variable +- in ~/.nx/config/keystrokes.cfg +- in /etc/nxagent/keystrokes.cfg + +If none of those files is accessible, the default configuration is used which +is the same as the old, traditional nxagent keybindings. + +File format +----------- + +The configuration file is XML with the following format: + +<!DOCTYPE NXKeystroke> +<keystrokes> +<keystroke action="fullscreen" AltMeta="1" Control="1" key="b" /> +<keystroke action="minimize" AltMeta="1" Control="1" key="space" /> +<keystroke action="minimize" key="Escape" Shift="1" /> +<keystroke action="close_session" key="F7" /> +<keystroke action="fullscreen" key="F7" Mod1="1" /> +<keystroke action="fullscreen" key="F6" Mod1="1" /> +<keystroke action="force_synchronization" key="f" /> +<keystroke action="fullscreen" key="space" Mod1="0" Mod2="0" Control="0" Shift="0" AltMeta="0" /> +</keystrokes> + +Each 'action' defines an action to be executed when receiving that keystroke. A +list of possible actions is given below. Some of those actions are only +available with debug builds of nxagent. + +Keys are given as a combination of 'key' and (optionally) a number of +modifiers. The key attribute is evaluated into a X11 key via the usual +XStringToKeysym function. A list of possible keys can be found in +/usr/include/X11/keysymdef.h, the names are specified without the leading +'XK_'. Evaluation is case-sensitive, so, 'space' and 'Escape' will work while +'Space' and 'escape' won't. + +Modifiers are given as boolean attributes, possible modifiers are Mod1, Mod2, +Mod3, Mod4, Control, Shift, Lock. Sensible combinations strongly depend on your +keyboard configuration, but usually you will need Mod1 and Control. Boolean in +this context means '0', 'false' and an unspecified attribute are false, anything +else is considered true. + +Everything in this file is case-sensitive. Unknown lines are ignored. +Keybindings are evaluated from top to bottom, so if a keybinding matches, other +keybindings further down will be ignored. The contents of the file replaces the +default keybindings, and only one file is read, no merging between different +configuration files is done. This also means that an empty or invalid configuration +file deactivates all keybindings. + +List of possible 'action' attributes: +------------------------------------- + +close_session +switch_all_screens +minimize +left +up +right +down +resize +defer +ignore +fullscreen +viewport_move_left +viewport_move_up +viewport_move_right +viewport_move_down + +Only in builds with certain debugging options enabled, ignored otherwise: +force_synchronization +debug_tree +regions_on_screen +test_input +deactivate_input_devices_grab |
