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.
