If it was ESC instead you'd get a +1. ;)

What if I told you that you can have both? For me it's ctrl when I hold it down and use it with another key and esc when I press it briefly. Can be set up on a Mac with Karabiner Elements.

If you told me that, I'd give you the +1. But Karabiner Elements doesn't work on my Arch box.

I have a udev rule that does the ESC mapping, but will have to try harder to see if I can make it do that on Linux.

Mine just does nothing.

Why not Command instead of Ctrl? Isn't that something that you use way more often?

Because I go used to use Emacs binding while on the terminal and VIM bindings for everything else. Ctrl + [ instead of ESC to change modes for me :D

I'm not that commenter but ctrl is my least favourite regularly used key to hit. It's not comfortable to reach with either my pinky or thumb. Command is basically where my thumb rests naturally, it's in prime position.

Yep, cmd is great where it is. If I compare cmd-shortcuts with identical ctrl-shortcuts, with normal key mapping, the ctrl ones strain my hand and pull my fingers away from the home row. The same cmd-based shortcuts do neither of those things. It's one thing Apple got very right, that everyone else is getting wrong.
