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 edit: link rot, now it is at 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” :-)
