Color 4 playheads in one keyboard shortcut

Multiple Playheads is a really smart feature, specially as Wipe Mode.

However is dificult to have 4 keyboard shortcuts and to think which image is one.

It will be way faster to have a single shortcut that toggles between playhead 1 to 4 alternatelly. So this will not steal mind power and we can go light fast.

It will be graphically easy to assign to key 1 to 4. But those are very disputed strokes because the same, all shortcuts want to have key 1 to 9 (color memories copy and paste, marker colors, flags, video track mutes, audio track lock... long list).

At last we have solved with exotic alt+control+ shift+1 to 4 combos, but this also steals mind power, spontanity and inspiration.

The difference against tracks, is that playheads are 4 only and easy togleable consecutively,

So here is my request: a keyboard shortcut that goes to "next" (and "previous" if you want, but I will not use it)
