A question about changing keybinds

[Ferth]

I don't think the game is set up to allow you to us the F key as a modifier.

When you are in the hotkey editor you highlight the hotkey that you want to modify and then press the key or key combination you want it to be. As far as I know ctrl, alt and shift are the only things you can use as modifiers. If you try to do F and another key it tries to use whichever key you release first.

If you have seen images where people have an entire hotbar set up with A or Q as modifiers they might be either using a third party program or editing game files directly.
