The command “editing” can re-enable Cisco IOS enhanced editing features for a specific line after they have been disabled.  On the other hand, the command “no editing” will disable this. This command was released in IOS 10.0. While these enhanced editing features are enabled by default, there will likely be times where one may wish to disable them. When the editing features are allowed, there are multiple command editing keys one may use such as Tab, which completes a partial command name entry.

To view commands that match the commands that one enters, a “?” should be entered. The command “return” will execute the command entered. By pressing the space bar, the next screen of output will be shown, and by pressing delete or backspace, the character to the left of the cursor will be removed. Pressing Escape and B or Escape and F, the cursor will be moved backward and forwards respectively. Pressing Ctrl-A will move the cursor to the beginning of the line, and Ctrl-E will move it to the end. There are multiple other commands that are used for editing, and they can be seen by following the below link. For a quick example of a command for the enhanced editing mode, to disable the mode for line 4, one would type……   Router(config)# line 4

                                               Router(config)# no editing
