No Ctrl+M stay
You can't create a shortcut to that command because of strange reason..
But there is a weird workaround.
You can create shortcut to user defined command. And a UserDefinedCommand can call the interal command..
* In UserDefinedCommand, Create a new command if "Interal Command" type. and select "Multi-Rename" module, and then "MultiRename" command
* Save Command
* Press Hotkey and assign a hotkey to that command
