ERASE PREVIOUS WORD

 Erases all of the previous word or all of the word the cursor is on.

 For example, if you are editing the following line:

     What I tell  you three times is true.
     |          | |      |
    [1]         [2]     [3]

    [1]  At the start of a line, erases only the carriage return for the
         previous line, if any; the current line moves up.  This is useful
         to erase blank lines to form paragraphs for FILL.

    [2]  Between words or on the first character of a word, erases the
         previous word -- in this case, "tell" and the trailing spaces.

    [3]  In the middle of a word, erases all of that word (same as ERASE
         WORD) -- in this case, "three" and the trailing spaces.

 To put back what you erased, use RESTORE WORD.
