Fires onAction for one named action - the programmatic counterpart of a physical key
press, without holding anything: an on-screen keyboard's Enter key feeds the confirm
action down the same signal a real key travels, so a prompt or menu cannot tell the two
apart. Deliberately no held/pressedThisFrame bookkeeping, because nothing is held.
