nano: Built-in Help

 
 5 Built-in Help
 ***************
 
 The built-in help system 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 system.
