When do you use the Cisco editing features?
There are a couple of editing features that are used quite often; some are
not used as much, if at all. Understand that Cisco didn't make these up;
these are just old Unix commands. However, Ctrl+A is really helpful to
negate a command.
For example, if you were to put in a long command and then decide you didn't
want to use that command in your configuration or that it didn't work, then
you can press your Up arrow key to show the last command entered, press
Ctrl+A, type no then a space, and press Enter, and poof, the command is
negated. This doesn't work on every command, but it works on a lot of them.
