Every once in a while I need to do some text editing in a *nix environment that has a minimum toolset installed.
Which means: use VI.
VI is a versatile text editor from the early *nix days, but it is not straight forward to use.
Since I don’t use VI often enough, I tend to forget some of the commands.
Time to share my favourite VI link: Mastering the VI editor.
The link points to the basic stuff, but the page contains most of what you ever want to know about VI.

PS:
If possible, I install the JOE text editor on systems where I am admin.
JOE uses WordStar like key bindings, and supports UTF-8. Talking about “something old, something new”
