What steps will reproduce the problem?
1. Define two or more keys.
(The next steps are purely for visual aid.)
2. Add an alert to one of them.
3. Open and press the key you have given the alert to.

Example Code:
jQuery(document).bind('keydown', 'a',function (evt){return false; });
jQuery(document).bind('keydown', 'b',function (evt){alert('foo'); return
false; });
jQuery(document).bind('keydown', 'c',function (evt){return false; });

What is the expected output? What do you see instead?
You should only see the alert once if the key was pressed only once. I see
the alert as many times as there are defined keys, in this case, three
times when 'b' is pressed.

What version of the product are you using? On what operating system?
hotkeys 0.7.9
Windows 7
with IE 8.0.x and Firefox 3.6.x

Please provide any additional information below.

Seems to be existent in all previous versions, though I haven't bothered to
test it on any versions previous of 0.7.6.

I consider this a major issue, both for performance and logical problems
this issue may cause.

If you're using jQuery 1.4.2, you should probably use js-hotkeys version 0.8
