Apple: #esc { margin-left: -30px }

It appears that is where the Touch Bar starts, so the Escape key/button probably cannot be moved further to the left.

There goes muscle memory.

The irony is that on my 12" MacBook 2016, the Esc key is yuuuge.

Vim users can use Ctrl-C instead of ESC.

For me it is actually easier to do :)

Ctrl-C in vim already has a purpose. It stops any and all background processing. I have needed and used it many times.
