If you ask to do a fix you need to read/verify what is done. If you are confident with your editor you go through long amounts of actions knowing your error rate is low enough to use less visual feedback loops.

I'd be curious how one gets to the error rate where they don't think they need feedback loops. Anyone can learn to touch type because the physics are deterministic and can expand from that to touch edit in something that isn't hopelessly WYSIWYG only.
