Agreed. Especially for the more advanced or less commonly used vim/ed shortcuts, adding them to my general Anki deck was invaluable. I went through "Practical Vim" by Drew Neil and added all the useful shortcuts to the deck, and whenever they would come up for review I would also try my best to put them to use that same day. The card format would be question/answer e.g. "how do you split a window vertically?"

I also used this approach to familiarize myself with the various unix tools I don't necessarily use daily (sed, awk, etc)
