Delete Previous Word

  Deletes the text at the left of the cursor to the start of a word.

  Example:

     The following shows the effects of the Delete Previous Word key with
     three different cursor positions on a line:

           LSE stands for  Language-Sensitive Editor.
           |             | |                    |
          (1)            (2)                   (3)

     (1)  At the start of a line, deletes only the carriage return at the
          end of the previous line, if any; the current line moves up.

     (2)  Between words or on the first character of a word, deletes the
          previous word.  In this case, deletes "for".  Spaces between
          the cursor position and the deleted word are deleted.

     (3)  In the middle of a word, deletes to the start of that word.  In
          this case, deletes "Ed". Spaces or tabs between words are not
          deleted.

  To reinsert what you deleted, use the Undelete Word key.
