[Feature Request] Key cycler

[nickjnaude]

I have been playing around with some FPS games, and noticed not many of them have (a) Previous/Next weapon key(s). Could there be something like the Action wheel, where we bind keys 1-8 (for example), and then, say L2 can be bound to "Previous Key in Key Cycler" and R2 will be "Next Key in Key Cycler". Subsequent presses of R2 will then press keys 1 to 8 in sequence, and L2 will cycle backwards pressing 8 to 1, The code will remember the last pressed key (Say key 4) and then R2 will trigger 5 and L2 will trigger 3?
