you can already do that.

please explain more about this behaviour. i suspect that what is
happening is that the b-format track doesn't meet the criterion for
"edit group equivalency" that is applied to regions. the region there
is probably not judged as equivalent-enough to the regions in the
other tracks. what is the history of this track?

yes, vscroll-during-select has been on the TODO list for a long time

that is not what "u" is bound to. it selects anything that has some
presence within the current edit range.
there is no select-at-edit-point.

the question is whether you're happy working with off-screen tracks
being edited ...

how would you want to do this that avoid the "extremely careful" part?

you can't change the length of a region like this, but you can change
its placement using the nudge clock and the nudge buttons or
you can change its length with absolute precision in its region
editor, but this will not map across all selected regions (since the
region editor is specifically for editing a particular region).

sounds like an interesting feature request. you can listen to A or B
on its own, but not the "end" or "start" of either.
