< p > < code > fc< / code > is a shell builtin to list and edit previous commands in an editor.
In addition to editing a single line (which you can also do with < code > C-x C-e< / code > ), it also allows you to edit and run several lines at the same time.
You use it like this:< / p >
< p > List previous commands< / p >

That works, but it is kind of a hassle.
A much more convenient alternative is installing this NetworkManager plugin:< / p >
