I name all my personal programs prefixed by the comma. I learnt it from someone on lobste.rs. No Unix utilities use the prefix in their name and it is a valid filename.

So I can type , and I am sure it's my program and I'm not running something else and it'll autocomplete among my list of programs.

This is a very cool idea, I always hesitate to add a lot of aliases to my zshrc since I never want to step on any toes.
