I’d like actual examples instead of “I work faster”, something like “I can move straight to the middle of the file with 7mv” or “I can keep 4 different text snippets in memory and paste each with a number+pt, like 2pt”, things that you actually use somewhat frequently instead of what you can do, but probably only did once.
Not to say that I think learning to edit Vim-style is worthwhile, but I think using Macros can be quite fun to do.
Recording a sequence of operations and then repeating it multiple times can potentially save a lot of editing time.
