For me, a lot of the value add comes from being able to open up files from a terminal, almost instantly, and make changes way quicker than I would through an IDE. It's also much faster when doing trivial and repetitive changes.

If you're interested you can look up how macros work in Vim. You can automate entire sequences of key strokes which goes beyond 'find and replace'. It's awkward at first but after you master it it becomes second nature and feels like you're working at the speed of thought.

When I have to use an IDE I usually try and install a Vim plugin.
