-'''Complete the current word before the cursor with words in the editor.
-
-Each menu selection or shortcut key selection replaces the word with a
-different word with the same prefix. The search for matches begins
-before the target and moves toward the top of the editor. It then starts
-after the cursor and moves down. It then returns to the original word and
-the cycle starts again.
-
-Changing the current text line or leaving the cursor in a different
-place before requesting the next selection causes AutoExpand to reset
-its state.
-
-This is an extension file and there is only one instance of AutoExpand.
