Alt-C / Alt-M is very usefull, but when I have to move 100 Files (while viewing 1000) it would be easier withough confirming always the destination.
Solutions
a) A new Menu-Entry "Set Copy/Move-Target" where you can enter these Destinations or select "[o] Ask every Time" (Option)
b) Two new Shortcuts for Copy/Move without asking.
a) is better

Thanks for all your efforts (with this suggestion or 100 others) and have a nice day!
