Keyboard and Gamepad button combinations
When mapping controls, multiple keys/buttons should be allowed to be used for an event.
For example, when mapping a gamepad, the original XBox mapping for "Next Weapon"/"Previous Weapon" and "Next Spell"/"Previous Spell" was "X + Right Trigger"/"X + Left Trigger" and "Y + Right Trigger"/"Y + Left Trigger", a mapping which is currently impossible.
Especially for gamepads, which have a much smaller number of buttons than a keyboard, the ability to map multi-key combination presses to events is essential to allow the player to fully utilize the game without switching to the keyboard.
