Back in 2013 I wrote about my favourite productivity boost in Emacs,
namely remapping Return to
which in combination with the classic remapping of
Control makes it really easy to get a grip on Emacs’s obsession with
the Control key.
In the original article I suggested to OS X (now macOS) users the tool
KeyRemap4MacBook, which was eventually renamed to
Karabiner. Unfortunately this tool
stopped working in macOS Sierra, due to some internal kernel
That was pretty painful for me as it meant that on my old MacBook I couldn’t upgrade to the newest macOS editions and on my new MacBook I couldn’t type properly in Emacs (as it came with Sierra pre-installed)… Bummer!
Fortunately 2 years later this is finally solved - the Karabiner team
rewrote Karabiner from scratch for newer macOS releases and recently
added my dream feature to the new
Karabiner Elements. Unlike in the
past though, this remapping is not actually bundled with Karabiner by
default, so you have to download and enable it manually from
That’s actually even better than what I had originally suggested, as
here it’s also suggested to use
CapsLock with a dual purpose as
Control when held down and
Escape otherwise. I have no
idea how this never came to my mind, but it’s truly epic! A crazy
productivity boost just got even crazier!
