Add hint for unidirectional ESC

[chreekat]

I had to trawl closed issues to find (happily) a solution to this use case. :)

P.S. Why is the README under .github? That seems like a bit of unnecessary lock-in.

I like the language you've used 😄

As for the README, the general workflow should be clicking on edit button at the top of the README.
You can always use projectile-find-file and similar functions for editing it on a cloned local version.

Thanks! :D

What I meant about the README is that it's buried under a hidden directory so anybody who clones the repo won't even necessarily know it's there. Putting it in .github makes it feel like it's a GitHub feature rather than a part of the repository. But it's not a big deal!
