# Why vi Rocks
|
|
|
|
**[vi](https://en.wikipedia.org/wiki/Vi)** is the _de facto_ standard
|
|
Unix editor, you find it in every *NIX derived OS.
|
|
|
|
Here you will find a collection of commands, command sequences in
|
|
[vi(1)](https://man.openbsd.org/vi.1)/[ex(1)](https://man.openbsd.org/ex.1)
|
|
or with 3rd party unitilities which make
|
|
**[vi](https://en.wikipedia.org/wiki/Vi)** rock. These all work
|
|
with at least [nvi](https://en.wikipedia.org/wiki/Nvi) 1.79 and
|
|
2.1.3 (unicode).
