== Syntax ==
KEY COMMAND ''key mask command icon [feedback]''
== Description ==
Binds a key with an arbitrary command.
== Parameters ==
: Sets the key to use. Not all keys work at this moment, but letters and function keys (as in "F1" should work.
: Is reserved for future use; just put a 0 in there.
: Is the command to run (don't forget the double quotes if needed)
: Is the ABSOLUTE location to the icon file to show on the keyboard.
: This optional string should appear with the line to be appended to the [[FEEDBACK_HANDLER]]. For example, if the FEEDBACK_HANDLER is 'xmessage -timeout 2 -center Launching ', the "feedback" string should be set to something like "gedit", so it shows "Launching gedit" on the screen. Note that omiting the "feedback" string disables the feedback for that KEY.
