Use to search for a text string in
  ■ The active window
  ■ The current module
  ■ All loaded modules
 
You can request an exact (case sensitive) match or a
whole-word match.
 
To change a string use the Change command instead.
 
Using the Selected Text command (Full Menus only) is an
efficient alternative when searching for a short (one line
or less) string in the active window.
