How to enable undo in nano?

Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite 1 How can I enable Undo in nano? I am using a ssh connection with a server. I can not update the version of nano that is installed on the server. Is there anyway to use GNU nano 2.3.1 to have Undo function? nano share | improve this question asked Feb 23 at 17:25 saeed mohammadi 11 4 I managed to find out the solution. I hope this helps. Use this command: nano -u Then use Alt+U for undo and Alt+E for redo. â saeed mohammadi Mar 16 at 22:28 This problem is just for the cases with nano 2.3.1. â saeed mohammadi Apr 15 at 16:36 This problem have been solved in newer version. â saeed mohammadi Apr 15 at 16:36 add a comment  | up vote 2 down vote favorite 1 How can I enable Undo in nano?
