I have a page with two button. When I press '5' I want that button1 to be clicked and on pressing '6' Button 2 to be clicked. Is it possible using jQuery?
Can I also handle Ctrl+5 in jQuery?

A:
Check out the event helpers in jQuery. Things like keypress and others.
In the keypress demo, when you enter a key into the box, you get to know the charcode number of that key.
For example 5 is 53 and 6 is 64

i've found the charcode is not always correct. press a number key at the top of your keyboard as opposed to the numpad numbers. also try it on different browsers and you get different results.

I actually tried this now, and got the same numbers on both numpad and top keys.

How can I detect the correct key cross-browser and click the respective button. An example is appreciated

A:
I recommend binding to the keyup event to prevent event duplicate firings. Here's some sample assuming buttons with Ids, button1 and button2.
$(function() {
$(document).keyup(function(e) {
if(e.keyCode == 53 || e.keyCode == 101) { //number 5
$("#button1").trigger('click');
} else if(e.keyCode == 54 || e.keyCode == 102) { //number 6
$("#button2").trigger('click');
}
});
});
Trapping CTRL+5 is very tricky and in the case of Chrome, it is intercepted by the browser.
