Aren't upper-case Dired keys reserved for potentially dangerous commands
because upper-case keys are harder to press (require holding Shift-key).
I guess if your command will ask additional information from the minibuffer
then either lower-case "c" or "z" are fine because they won't run immediately.
"Z" would be good too if you could improve it in a backward-compatible way.
