The keybinding that runs the correspondingly-numbered
command in /apps/metacity/keybinding_commands
The format looks like "&lt;Control&gt;a" or
"&lt;Shift&gt;&lt;Alt&gt;F1.
The parser is fairly liberal and allows lower or upper case,
and also abbreviations such as "&lt;Ctl&gt;" and
"&lt;Ctrl&gt;". If you set the option to the special string
"disabled", then there will be no keybinding for this
action.
