A simple way to add key handling to jquery

To start just add $.keyNav();

Then you can do fancy stuff like:

$.whenPressed('j',function(){ alert('you pressed j');});

$('h1').whenPressed('h',function(){ $(this).hide();});

if you pass it a string it will look through its dictionary for the keycode. If passed an integer, it will assume thats the keycode and use that

I also added some helper methods:

$('a:first').navigateTo();

will set the pages location to anchor's href.

there's also tests for the keycode

$.isLetter(keyCode) will check to see if the key code is a letter

$.isNumber(keyCode) will check to see if the key is a number, including the numpad

$('div').scrollTo() will scroll to fit the element in the window if its outside the viewable area

$('div').find('h1').or('p') will return h1 if it exists, if not it will look for p

You can also suspend watching the keys (it does automatically when you enter an input field) with

$.keyNav.unwatchKeys();

then start again

$.keyNav.watchKeys();
