Is your keyboard one of those that you have to press some Fn key to make the f'n function keys work?
Test out your F keys in something, see if they do what you expect.
AHA! I'd tried pressing the Fn key at the same time as the others and it didn't work. Pressing and holding it first and then the other three together works.
