Can I capture the CTRL key when a click event occurs?

Yes, you can with NN4, NN6 and IE4+. Just check 
  event.ctrlKey
for NN6 and IE4+ and
  event.modifiers & Event.CONTROL_MASK
for NN4.
Complete example:

<FORM>
<INPUT TYPE="button" VALUE="a button"
       ONCLICK="var ctrlKey = document.layers ? event.modifiers & 
Event.CONTROL_MASK :
                  event.ctrlKey;
                alert((ctrlKey ? 'Ctrl-' : '') + event.type);"
>
</FORM>
