How to edit multiple regions in one Piano Roll window

Question

I edit multiple regions in one Piano Roll window at the same time. (It is very handy way of editing especially in huge orchestra projects.)
I can see midi contents of all selected regions in Piano Roll at the same time.
1) But how to choose certain one region of many selected to edit it?
2) And how to edit all at once?
Hope the questions are clear enough.
Thanks.

First of all, the Piano Roll has two mechansim, of what it is displaying.
Selected Track: This displays all the Regions that you select in the Tracks Window
One Track: Selecting one Region in the Track Area displays all the Regions of tha tTrack in the Piano Roll. If you select multiple Regions in the Tracks Window, then the last selected Regions counts.
Whatever Regions are now displayed in the Piano Roll Editor can be edited. Select the MIDI Events and apply the command.
You can also apply edits directly to the selected Regions in the Tracks Window.
I explain all those little details in my graphically enhanced manuals ("Logic Pro X - How it Works")
One thing to be clear about:
Tracks Window: Any edit is applied to the selected Regions
Piano Roll Editor: Ay edit is applied to the selected Events
Hope that helps
