If you're playing a HA then "F" will activate your over-shield, if playing a engi it makes you throw an ammo pack and so on, because "F" it just the "use ability button" (with the exception of LAs of course).

If in a tank it doesn't matter what class you are (though engi's normally one of the best because they can jump out and repair things) so "F" as well as the "X" button becomes the vehicle's "use ability button" (becausse you can't use a class ability when in a vehicle) if you have one equiped to activate.
