Many thanks for your reply.
You confirmed that there is actually no auto function to help me being lazy...
I tried your keyboard soluce but I had to adapt it to my default french keyboard; not so difficult except for the align command because I got 2 sub-menus having the same shortcut !
In the menu "Pistes" (=tracks), the 2 following submenus have the same "simple keyboard shortcut" (A):
ucune piste muette (=no silent track)
ligner les pistes (=align tracks)
and naturally the first one comes when I press the key "A"...
So I tried to look if there is a way to set manually a specific shortcut for the function "Align track" but any of these alignment sub-menu and functions do appear in the Preferences-Keyboard setup screen.
So I can now go with a mix of shortcuts and arrows; I'll do it this way:
K > ENTER > Down > ENTER > Alt+P > A > Down arrow > Right arrow > C
Thanks again for your support.
nb: yes, as proposed, please add my vote for the "import Appended" as it may solve the above, many thanks.
