BR or FR? using the B-shortcut

[midi-man]

Hi!

I don't really understand the logic behind the B-shortcut (move selected clips to back of z-order).

At the moment I'm trying to put midi-clips on top on each other as a subsitute for future folder-tracks. The problem is that if I put more than two clip on top of each other it seems impossible to get some of the clips to the top for editing.

I guess I want to change the B-shortcut to:
"move the top clip to back of z-order"

Greetings midi-man
