Syntax:  LOWERCASE

  Changes the current word or the selected range to lowercase.

  If the word contains both uppercase and lowercase characters, LSE
  changes all letters to lowercase.  If the cursor is between words,
  LSE changes the following word to lowercase.  If a selected range is
  active, all the words within that range are changed to lowercase.
  The cursor then moves to the start of the next word after the
  selected range.
