Did you catch one interesting bit in the last post? The undo shortcut in Paint and other apps in Windows 1.0 used to be Shift+Esc:

This reminded me that the classic Ctrl+Alt+Del shortcut was initially Ctrl+Alt+Esc. Except, people apparently invoked it a bit too often by accident, so it was split to require two hands for extra safety.

When you look at the keyboard for the original PC, it all makes sense. Esc is at the edge of the main typing block, and in line with all the modifier keys. It would make sense to build a system around this, and it’s interesting to imagine the Esc Kinematic Universe that never happened.

Don’t get me wrong: I think it’s good that it didn’t. ⌘Z or Ctrl+Z are much easier to get to than Shift+Esc, especially in concert with cut/copy/​paste next door – that system introduced by Apple Lisa and Mac teams deserves endless trophies and infinite accolades. (In case you are curious, Windows 1.0 used Delete for Cut, Insert for Paste, and… F2 for Copy.)

But it has always been peculiar to me that Esc isn’t seeing more use. I see Backspace tasked with all sorts of modifier key combinations in various apps, but Esc – equally available on the other side, and even easier to target on some keyboards – is often left alone.

Poetically, given the beginning of this story, it was Mac that grabbed ⌘⌥Esc for force quit:

There is a nice thoughtful design element in that window that’s worth calling out: the hint line the bottom.

Why, of all places, would this window go out of its way to announce its own shortcut after you already figured out how to open it? I think this might be for a similar reason airlines repeat the safety announcements before every takeoff. If your computer goes haywire, if one of your apps starts hogging resources, if the UI slows down so much any action takes forever, it might benefit you if somewhere in the back of your head exists one small bit of information: “ah yeah, I don’t know how I know this, but I think I’m supposed to press ⌘⌥Esc now.”
