capture event when ctrl key is pressed

Hello,
I want to capture the event when the <ctrl> key is pressed.

How can I do that ?

This is under IE 6 (I don't have any other browsers, so someone else
will have to chip in).

A onkeydown event is fired when the CTRL key is pressed, but the
event.which and event.modifiers properties are undefined (even when a
letter key is pressed). This means that there is no reliable way to
detect it. The onkeypress event doesn't work with modifier keys
(ctrl, alt, shift, etc).

Do Mac keyboards even have CTRL keys?

Both navigator 7 and explorer 6 can detect the onkeyup event, and do
recognise the control key. onkeydown and onkeypress may also be
supported. However, control+[key] combo keystrokes are rather more
difficult to detect. I haven't tried.

This works completely in Mozilla (ns), have problems in IE when only using the ev.ctrlKey && ev.keyCode, it's like it won't capture the ctrl unless the shift or alt key are pressed too. Annoying!

and then put this in the body tag...

onload="document.onkeypress=captureKeys;"
