Audio Comping - Delete all the left-out-of-the-comp parts

When comping audio,
How can I Quickly delete all the left-out-of-the-comp parts?

I.e. in the attached screenshot,
delete all the lighter-pink parts which are not in use in the comp.

The reason BTW, I find it less confusing and less mistakes to not have layers
before the final touch of the comping - find the exact parts’ positions and crossfades.

So what is the fastest way to delete all those non-chosen parts in the lanes?
Rather than to select them manually with the mouse.


Found it.
Menu Audio - Advanced - Delete Overlaps

what a magnificent tool…
