Honestly, for me the split keys are just muscle memory at this point, same as 'hjkl' in Vim. Same with my prefix- I used backticks for the longest time, and now I use Ctrl-Space, but I generally don't think about it anymore. (Along the same lines, I screw up and occasionally type "jj" or ":wq" in message boxes out of force of habit from Vim.) It's weird- as I'm typing this comment, I tried issuing "Ctrl-Space %" a couple times just to test, and I get a very slight mental "misstep" because the comment box isn't splitting in half!
