Support combines selections from the register with the current ones and the other way around.

This would help a lot with manipulate complex multi selection. From Kakoune's keys docs:

Alt-z combines selections from the register with the current ones, whereas Alt-Z combines current selections with the ones in the register; a menu is then displayed which waits for one of the following additional keys:

• a append selections.
• u keep a union of selections.
• i keep an intersection of selections.
• < select the selection with the leftmost cursor for each pair.
• > select the selection with the rightmost cursor for each pair.
• + select the longest selection
• - select the shortest selection.

(I don't think <, >, + and - is useful)

This require #54 to be done.

Pepper does not really have a way to save cursors to a register.
What it does is save a path + line + column (main cursor's position).
It could indeed be extended to support multiple cursors as #54 suggests.

However, I'm not sure how that would work when trying to combine cursors from another file.
Say you're on buffer a and bookmark it's current cursor state to register p.
Then you open buffer b.
Now would 'append cursors from register p' ignore that they're buffer a cursors?
Or do nothing in that case? Or even just go to buffer a and restore its selections?

Sorry for the late reply.

So I have reinstall Kakoune and try this out:

• Save selections to the register '^' (default marks register on Kakoune) on buffer A.
• Open buffer B.
• Press Alt-z or Alt-Z.

Both display this message:

We could make Pepper behave the same.
