Handling key-press events (F1-F12) using JavaScript and jQuery, cross-browser

Question

I want to handle F1-F12 keys using JavaScript and jQuery.

I am not sure what pitfalls there are to avoid, and I am not currently able to test implementations in any other browsers than Internet Explorer 8, Google Chrome and Mozilla FireFox 3.

Any suggestions to a full cross-browser solution? Something like a well-tested jQuery library or maybe just vanilla jQuery/JavaScript?

I agree with William that in general it is a bad idea to hijack the function keys. That said, I found the shortcut library that adds this functionality, as well as other keyboard shortcuts and combination, in a very slick way.

Single keystroke:

shortcut.add("F1", function() {
    alert("F1 pressed");
});

Combination of keystrokes:

shortcut.add("Ctrl+Shift+A", function() {
    alert("Ctrl Shift A pressed");
});
