I never really liked how my hotkeys plugin (that allows things like $('body').on('keydown', {keys: '^A'}, function() {alert ('Control-A!'); })) worked internally, and it didn't allow multiple handlers on a single element for a given key combination, and required initialization. I went back and looked at it some more, and studied John Resig's hotkeys, and came up with a simpler, better version. Use is largely the same, but there's no $.keymap.hotkeys('keydown') to initialize, and you have to explicitly remove handlers with $().off() rather than replacing with a new handler.
See the code.
