nano: The Help Viewer

 
 4 The Help Viewer
 *****************
 
 The built-in help in ‘nano’ is available by pressing ‘^G’.  It is fairly
 self-explanatory.  It documents the various parts of the editor and the
 available keystrokes.  Navigation is via the ‘^Y’ (Page Up) and ‘^V’
 (Page Down) keys.  ‘^X’ exits from the help viewer.
