nano: The Cutbuffer

 
 4.3 The Cutbuffer
 =================
 
 Text can be cut from a file, a whole line at a time, by using the ’Cut
 Text’ command (default key binding: ‘^K’).  The cut line is stored in
 the cutbuffer.  Consecutive strokes of ‘^K’ will add each cut line to
 this buffer, but a ‘^K’ after any other keystroke will overwrite the
 entire cutbuffer.
 
    The contents of the cutbuffer can be pasted back into the file with
 the ’Uncut Text’ command (default key binding: ‘^U’).
 
    A line of text can be copied into the cutbuffer (without cutting it)
 with the ’Copy Text’ command (default key binding: ‘M-6’).
