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.
Multiple cursors are fantastic for certain use cases, but will not help you when each line needs a different input – if you’re swapping arguments in function calls, if you’re replacing one bracket type with another around contents of arbitrary length, etc.
Mind you, if your objective here is to not learn a new thing, then you can just go ahead and do that, you don’t need an excuse.
Yeah, I usually do that with regexp replacement in other editors, but sometimes it’s too hard to express as a regular expression
