Why is everyone keep saying that Esc key is gone, OS X allows you to customize that new touch bar, you can make the Esc button to always show on the same spot you had it before...
I put a piece of double-sided sticky tape on my ESC key just to make me notice how often I hit it. When I'm editing, it's all the time.
The seeming last-minute addition of a remapping feature for ESC in OSX leads me to believe that the software people at Apple were railroaded by some hardware folks. Hard to believe that whole teams using Emacs / vim were ignored, but I've seen it happen before.
Well, the guy in charge (Ive) is basically a hardware person.
What do you use ESC for in Emacs? I used to occasionally use it to hit M-x, but now I use key-chord.el to map 'xx' to M-x and it's all good.
Maybe Apple has decided to kill off the pesky Emacs and vim users. Yeah. :-)
