  Syntax:  ERASE WORD

  Erases a word at the current cursor position.

  This command erases the entire word the cursor is on, regardless of
  the cursor's position within that word.  You can terminate a word
  with tabs or characters not specified for language identifier
  characters.  A word can consist of identifier characters and trailing
  blanks, or it can consist of a single nonblank, nonidentifier
  character.
