I'm learning Emacs for class, and I was wondering: do you use the same hand to hit the command/meta keys? For example, when I'm doing C-n or C-p, I am currently hitting the command key with my left hand, but the identifier with my right. Is this the normal way, or do most people use one hand to execute a command?
I believe the general ergonomic advice is to hit the modifier and "normal" key each with a different hand, so you're doing it right. I try to follow that guideline, but I frequently make exceptions. This is especially true since I have caps lock mapped to ctrl, so I favor that left ctrl button regardless of the other keys I'm pressing.
First off, the Mac "Command key" is not involved with "C-x". "C" is for "control". "Command" is often bound to the Emacs "Meta" key, which would be "M-x".
For C-x I generally hit Control with my left pinky and X with my left middle finger: since C-x is a "prefix" key, there's going to be another key I hit later and that will generally be hit with my left index finger.
However for the C-x C-s sequence I use my left index finger on X and my left middle finger for S. Same with C-x C-q.
For M-x I use my left thumb on the Meta key (my Mac's "Option" key in my case) and my left index finger on X.
Just like playing piano, there is no "right" way to map your fingers to the keys (everyone's hands are different, after all). If something feels wrong or is hurting, try using different fingers.
Yes. Always hit the modifiers with the opposite hand. This is taught in every keyboarding class, and applies to all modifiers, even Shift. This will make you a faster typist, and your hands will feel much better. Some newfangled keyboards don't include two sets of every modifier, so don't buy those. :)
