Xbindkeys is a program that allows you to launch shell commands with your keyboard or your mouse under the X Window System. It links commands to keys or mouse buttons, using a configuration file. It's independent of the window manager and can capture all keyboard keys (ex: Power, Wake...).

It optionally supports a guile-based configuration file layout, which enables you to access all xbindkeys internals, so you can have key combinations, double clicks or timed double clicks take actions. Also all functions that work in guile will work for xbindkeys.
