That would be great. It's probably a failure of my imagination, but I can't
think of when the example with 'e' would help (it's not often that the
current buffer is empty here). And if you're going to have a tip to replace
a builtin command, you should have a couple of useful examples.

If anyone can suggest some simple-but-useful examples for abbreviations that
might illustrate this tip, please post.

As a confirmed curmudgeon, I personally would avoid redefining builtin
commands - life is sufficiently exciting without wondering what's going to
happen when I use ':e ...' on different systems. The comment shows a useful
'wx' abbreviation, and I'm thinking that the tip could have a slight change
in emphasis to say you can define abbreviations for commands, and you can
even redefine builtin commands. At any rate, I would not bother trying to
make a reliable replacement for ':e' that works as wanted in the tip.

The tip might also mention the reasoning: Whereas you could map a key to
perform a useful operation, it can be easier to type a command with a name
that you can remember, rather than have lots of complex and essentially
meaningless key combinations for different operations.

Magnificent - I was getting worried<g>.
