Interesting. Because resting my left hand on the keyboard my pinky is on shift, ring on a, middle on e, index on f.

I also use tmux. I do a remapping to ctrl-s because I use ctrl-a (and ctrl-e) all the time to go to the beginning and end of lines. And let's be real, the normal behavior of ctrl-s (suspending) is not something I'm ever going to use on purpose.

But also I'm not using a mac.

> I hate having to press both keys with one hand for Ctrl key combos (ctrl-a being the only exception).

Do you not use panes? In vim? Because I use those quite a lot.
