Oh please, not vim again. Now you are not even supposed to use the already ridiculous hjkl mappings. It's really amazing to me to see this sub-culture attach itself to an editor that was designed as it is BECAUSE THE AUTHORS DID NOT HAVE KEYBOARDS WITH MORE KEYS ON THEM! "hjkl is faster than reaching for the cursor keys". Holy frigging crap! Really? You are so good as a developer that MILLISECONDS make a difference?…
Like you say when your jumping around a lot then it matters less. When you're typing a lot then it does matter to keep your fingers on the home row.
