"Names" are aliases, similar to soft links; "udd" is a name for
"user_dir_dir" so ">udd" and ">user_dir_dir" point to the same directory.

>user_dir_dir>SysAdmin>admin    or   >udd>sa>a   is  ~root/

Circulating back to the original question, backslash is used as an escape
character on Multics.  "\f" is end-of-file-ish, used eg to leave input mode
in text editors.

And I wonder if the 'dd' directory on PDP-7 Unix owe anything to 'udd'?
