I'd like to set "U" as alias for UNODO and to reserve "A" for ARC.
But if I go into the Alias list and try to make obtain the result written above, it doesn't work.
"A" remains the obliged shortcut fo UNDO and cannot be reserved for no other command.
In particular, I can write "A" in correspondence of other commands and it remains correctly written in the list associated to the command I wanted, but when i push "A"+ENTER it works like UNDO in any case.

How could I solve this little issue? Thank you

PS: I use DS in Italian language and the translation of Undo is Annulla
