Problem with keybind causing camera to not rotate

Check here if the combination you're trying is detected by hardware - most keyboards typically aren't wired to detect arbitrary combination of alphanumeric keys pressed (outside of WASD), but 2 should definitely be within the capabilities of almost every keyboard.

Space and F were both recognized but it might just be a problem with the keyboard I'm using, it's been acting strange. Especially since I've asked around and it doesn't seem anyone else has had the same problem as me.
