nano: Using the Mouse

 
 3.7 Using the Mouse
 ===================
 
 When mouse support has been configured and enabled, a single mouse click
 places the cursor at the indicated position.  Clicking a second time in
 the same position toggles the mark.  Clicking in the two help lines
 executes the selected shortcut.  To be able to select text with the left
 button, or paste text with the middle button, hold down the Shift key
 during those actions.
 
    The mouse will work in the X Window System, and on the console when
 gpm is running.
