I am of course aware of git aliases (e.g. because OP uses them a lot) but it never occured to me specifically to shorten git to g and find a way to keep autocomplete working.

However, since these are by far my most typed commands (specifically, probably 40% of my executed commands are `s`), I strongly care about the difference even between 1 and 3 keystrokes.

Thanks for your feedback. I wonder if the downvote was because of using bash aliases or for something more substantial...
