Incrementer for (config driven) ordered lists.

A little spin-off from #2977

Code-wise this looks fine to me but IMO toggling a boolean is conceptually different from increment/decrement. Even as a standalone binding or feature I think this is too specific: I don't see much value over editing the boolean by hand.

I understand your concern about it being "conceptually different", however there are only so many keybindings to remember and using C-a to scroll thru an ordered enumeration would make sense to me. Eg. [0,1,2,3,...], [true,false], [yes,no], [a,b,c,...], [red,green,blue,...16 base colors/ or colors already in use in eg. a theme file]. Agreed it will not always make sense to use this feature, however it would be up to user to choose what feature to use/apply when?

another sequence I can think of is musical notes: c, c#, d, e, f, f#, g, a, b

This is way too niche for core, in my opinion.

I am closing this as stale as this PR has a lot of conflicts. I also don't see us going forward with this as it's too niche for core. Thjs can already be implemented with pipe instead and could be a simple function in your keymap once #10389 lands.
