[Suggestion] Make "Jump 1 Frame" shortcuts repeat when holding key

[Cub0use]

I use the "Jump 1 Frame Forth" and "Jump 1 Frame Back" shortcuts with Mouse 4 and Mouse 5, so I'd like them to repeat for lack of better word when I hold a key down, rather than having to release and press again.

-To navigate the timeline more precisely, maybe a longer interval of ~0.2s after the first action would be suiting, before repeating the action in shorter intervals. That would also cater to people that prefer to press and release to jump one frame at a time.

-Stop jumping forth when reaching the end of the animation length to easily stop there. Release and press again to go beyond the animation length.
