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 + This terminates the session. +switch_all_screens +minimize + This will minimize the client window (even for fullscreen sessions.) +left +up +right +down +resize + This action switches between the auto-resize and viewport mode (static size). The default is auto-resize. In viewport mode one can use the 'viewport_move_up', 'viewport_move_down', 'viewport_move_left' and 'viewport_move_right' actions to move within the image. +defer + Works like 'ignore' to make some keys be ignored/defunct inside the session. +ignore + Makes it possible to add 'ignore', as in nothing happens when certain keys are pressed. +fullscreen + Switches the client window into or out of fullscreen mode. +viewport_move_left + Moves the image viewport to the left. +viewport_move_up + Moves the image viewport up. +viewport_move_right + Moves the image viewport to the right. +viewport_move_down + Moves the image viewport down. + +Only in builds with certain debugging options enabled, ignored otherwise: +force_synchronization + Forces the drawing of elements to be synchronized which can fix some visual bugs. +debug_tree +regions_on_screen +test_input +deactivate_input_devices_grab |
