xbindkeys - a grabbing keys program for X

xbindkeys [ options ]

XbindKeys is a program that grabs key and mouse button events in X and starts associated shell commands.

Available command line options are as follows:

Print a default rc file
Use an alternative rc file
Short help on options plus version/author info.
Set X display to use
More information on xbindkeys when it runs

Identify one key pressed (useful for configuration)

Identify multi key pressed (useful for configuration)

size and position of window with -k|-mk option

don't start as daemon

If guile support has not been disabled:

Print a default guile configuration file

Use an alternative guile configuration file

XBindKeys default configuration file is at $HOME/.xbindkeysrc, used only for one user.

The configuration file consists of commands in double quotes, and associated keys in the next line.

Comments are started with a pound (#) and extend to the end of the line.

You can see a default configuration with --defaults

The program expects combinations of keysyms to be used by using plus (+) characters to combine them together.

The format of a command line is:

"command to start &"

associated key

To specify an associated key, you can use `xbindkeys --key` or

`xbindkeys --multikey` and put one of the two lines in the configuration file.

A list of keys is in /usr/include/X11/keysym.h and in /usr/include/X11/keysymdef.h. The XK_ is not needed.

List of modifiers:

Release, Control, Shift, Mod1 (Alt), Mod2 (NumLock),

Mod3 (CapsLock), Mod4, Mod5 (Scroll).

The release modifier is not a standard X modifier, but you can use it if you
  want to catch release events instead of press events. Modifiers are not case

By defaults, xbindkeys does not pay attention to the modifiers NumLock, CapsLock and ScrollLock. Add the lines below in the configuration file if you want to pay attention to them.

keystate_numlock = enable

keystate_capslock = enable

keystate_scrolllock= enable

# control+shift+q starts xterm


control+shift + q
# Menu key starts xbindkeys_show


# Control + mouse button 1 starts xterm


Control + b:1
# Control+Shift+a  release event starts rxvt


release+control+shift + a
# Control + mouse button 2 release event starts rxvt


Control + b:2 + Release

A scheme configuration can be used if guile support has not been disabled. The standard configuration is loaded only if the scheme configuration is not available.

For more details, please see here
Note: The guile configuration file is prefered for non trivial
configurations, for example double click, timed click or key combinations.
The default location is ~/.xbindkeysrc.scm
Use xbindkeys --defaults-guile for more details.
And xbindkeys --defaults-guile > ~/.xbindkeysrc.scm to use this method.

xbindkeys reloads the configuration file if modified. Send a HUP signal to force reloading:

killall -HUP xbindkeys

When a HUP signal is sent to xbindkeys, changes take effect only after moving the mouse.
