Make 'Select note/rest above' (and below) work on list selections

[avvvvve]

Your idea

The shortcuts 'Select note/rest above' and 'Select note/rest below' (Alt+Up and Alt+Down respectively) currently only work on single-note selections, not list selections of multiple notes.

Problem to be solved

The tricky part will be handling more irregular list selections, but we could do something like the following:

If you start with this...

One 'Select note/rest above' would get you this...

Running it again would get you this (and running it any number of times more, since the selection is now already at the top of each chord)...

Then, one 'Select note/rest below' gives this...

And one more gives this...
