TODO:
|
|
add queue support (as in gmail) e.g. 'x' then 'y', etc.
|
|
add mouse + mouse wheel events.
|
|
|
|
Usage:
|
|
jQuery.hotkeys.add('Ctrl+c', function(){ alert('copy anyone?');});
|
|
jQuery.hotkeys.add('Ctrl+c', {target:'div#editor', type:'keyup', propagate: true},function(){ alert('copy anyone?');});
|
|
jQuery.hotkeys.remove('Ctrl+c');
