+1; Mac key bindings is a s**show.

BetterTouchTool is my solution. Incredibly hacky and time consuming, but I'm happy with my setup. Now my key bindings are 95% equal across Linux and Mac, so I don't have to spend too much cognitive energy having to remember which system I am using.

I wish we had some sort of key maps that you could copy between machines & OSes, and all the key bindings would work the same way.
