I need an on-screen keyboard that only has 3 keys (Shift, Ctrl and Alt).

[yetoyeto]

Could someone point me in the right direction to a sample script that I can modify to make an on-screen keyboard that only has 3 keys (Shift, Ctrl and Alt)? I would like to be able to click on these keys and "fool" my computer into thinking I am holding these keys down.

Thank you in advance for any help,
yeto
