This will most certainly work.

But what was causing the error in your code was the then in the second line as Dabbler said. If you want to use then, it must be on the same line as if, along with any lines you want to protect with the conditional.

well if you use the scancode() command and print it to the screen whenever you press a key it will come up with a number.

e.g. if pressed a it would return 30 which i could put into keystate(30) and that will watch the keystate and when a is pressed you can do stuff

e.g.
if keystate(30)
`do stuff
Endif
