The Escape key is pretty essential to the Mac. You can use it to, well, escape from the current window/view/text field. You can use it to dismiss some dialog boxes. It can even be used to force-quit an unresponsive app. And that’s before we get to the Vim text editor, which is as dependent on the Escape key as Jony Ive is on new kinds of aluminum. So why did Apple remove the physical MacBook Pro Escape key when it introduced the Touch Bar?
Apple made that move, much to the despair of some users, back in 2016. Now, in the new 16-inch MacBook Pro, the Escape key is back. But what if you have a perfectly good previous-gen MacBook Pro? Are you really going to spend close to $3,000 just to get your Escape key back? No, you are not. Instead, you are going to repurpose the Caps Lock key, and turn it into an Escape key.
