TheBrownDragon: Not sure if the problem is that you don't have an F10 key on your keyboard or if pressing it does nothing.

If it's the latter, some keyboards (stupidly IMO) default to the function keys not working normally.

On these keyboards there's usually a button called "F Lock" or something similar.

If there is, try pressing "F Lock" before hitting "F10"

The "F Lock" key works much like a "Caps Lock" or "Num Lock" in that it toggles function keys into working as regular function keys (e.g. F10) or 'special' keys specific to that keyboard such as "Undo" or "Print"
