Good question. I often (not always) start the custom command name (script or alias) with the same letter as what it abbreviates, and if memorizing were my goal and that didn't help enough to remember them, I might do as you suggest. But I have enough to remember as it is, so I make backups of my scripts (as with everything personal on my main computer) using tar/gz/gpg/rsync/scp, optical media, etc., so I can refer to them when memory fails. Overall, I'd have to guess it depends on the person and the priorities, and how well one way works for you vs. the other. I currently always use a computer under my control, and over time, enough has stuck in my memory. I also want to save my hands by making things ergonomic (shorter to type when practical), as the hands are useful in the long-term. :)
