jQuery.Hotkeys plugin lets you easily add and remove handlers for keyboard events anywhere in your code supporting almost any key combination. It takes one line of code to bind/unbind a hot key combination.
Example:
Binding 'Ctrl+c'
$(document).bind('keydown', 'ctrl+c', fn);
Unbinding 'Ctrl+c'
$(document).unbind('keydown', 'ctrl+c', fn);
