Detecting cmd+r and cmd+w (and ctrl+r and ctrl+w) via Javascript?

Question

I am looking for a way to detect cmd+r and cmd+w (also ctrl+r and ctrl+w) in my application.

This site does it http://gpl.internetconnection.net/vi/. The source is a nightmare though. If I don't find a quick answer, I'll look through that.

Does anyone have a link or example?

Answer 1

using jQuery:

$.ctrl = function(key, callback, args) {
    var isCtrl = false;
    $(document).keydown(function(e) {
        if(!args) args=[]; // IE barks when args is null

        if(e.ctrlKey) isCtrl = true;
        if(e.keyCode == key.charCodeAt(0) && isCtrl) {
            callback.apply(this, args);
            return false;
        }
    }).keyup(function(e) {
        if(e.ctrlKey) isCtrl = false;
    });
};
