I went off WSAD a while ago and EDSF didn't really fix the problem, so I went right on over to RFDG. This got me far enough away from using shift and tab in games so as not to clash with going into the steam overlay, but no so far as to run out of buttons for my pinky before hitting the space bar, Z is now shift and I have W and E instead of tab, unfortunately ALT started causing other problems and I've now taught my pinky to be able to go between Z and X quite easily.
I also find WASD weird to say, I've always said up, down, left, right and so I've also always said WSAD, probably because it's the more common order they appear in control lists.
