After years of abusing my little finger for using Ctrl & the RSI that goes with it, I tend to use alt/meta with my thumb more and more nowadays, for this I make it usable in insert mode also, this is probably one of the oldest bits of my .vimrc "quick window movements map map l map k map j map h imap li imap ki imap ji imap hi
Only problem with those imaps is that now you can't type ì, ë, ê, or è. Vim is pretty dumb about utf-8. I'd also suggest using instead of the ...i dance. Edit: "The way [Vim] stores alt+letter in its input queue collides with UTF-8/Unicode handling" -- LeoNerd in freenode/#vim at 2013-04-15 15:22:29
Obviously not very helpful to people not on a Mac, but I don't have to go through Alt mappings at all.
