A screen cast utility that displays your keyboard and mouse status

http://code.google.com/p/key-mon/

Key-mon is useful for teaching since it shows the current status of your
keyboard and mouse and you use them in another application. No longer do
you need to say 'Now I'm pressing the Ctrl-D key', your students can just
see the keystroke for themselves.
