Yeah, I do something kind of similar, using Dash [1] snippets which expand to full commands.

Since I'm almost always on my mac, it means they're available in every shell, including remote shells, and in other situations like on Slack or writing documentation.

I mostly use § as a prefix so I don't type them accidentally (although my git shortcuts are all `gg`-consonant which is not likely to appear in real typing).

I was nearly 10 years old (i.e. as a Fish user) when I learned about abbr. I used to use functions for everything. :facepalm:

Came here to mention just this, all the more as the article mention that the author is considering a move to Fish.
