WORD - (1)
 Moves the cursor forward or backward by a word, depending on the current
 direction (see ADVANCE and BACKUP).

 CHNGCASE - (GOLD 1)
 Changes the case of a range of characters as follows:

     1.  If the select range is active, the case of each letter in the select
         range is changed.
     2.  If 1 does not apply and the cursor is positioned on the current search
         string, the case of each letter in the search string is changed.
         This does not apply if a repeat count greater than 1 is given.
     3.  If 1 and 2 do not apply, then the case of one letter is changed.
         If the current direction is ADVANCE, the cursor moves forward one
         character after the change of case occurs.  If the current direction is
         BACKUP, the cursor moves backward one character before the case change
         occurs.
