Control+click action in javascript.
Gives you control to perform actions when the control key and the mouse button is clicked in the same time. Something similar to selecting elements in Windows with ctrl+click.
Just change the event.ctrlKey to event.shiftKey to make it shift+click. If you don't get it don't worry the snippet contains the demo for shift+click too.
You may need to change the event.which though 1 = left click, 2 = middle click, 3 = right click(at least in firefox 1.5.0.5)
