    ** Note:  many commands like  D,  Y,  dd,  x, etc.  can be preceeded
              by a number to denote how many characters, lines, words,
              etc. are to be modified.
    The set command:  I've found the `set` command very helpful.  You should
                      type  :set all  in  vi  to get a list of all the
                      options.  (I've found `set autoindent` to be especially
                      nice when writing programs).
