It works on El Cap too. But it's another config file. I'll dig up and post it shortly.

Both of the modifier keys (Snap and Pop) work just like Shift and Control. You hold them down to get the other layer. On mac keyboards you can't count on more than 2 keys pressed at the same time so a Shift + Snap + A might (or might not work). I had a few failed attempts at combo modifiers before I decided they wouldn't be reliable enough (at least not on my mac pro).

That's nice. One of my goals was to make it easy to remember the key locations so I ended up with <{[(/\)]}> all on one row.

Yes, if you hold down J and Semicolon and then hit the a button on a macbook pro you will notice it isn't picked up. It is a hardware limitation on most keyboards. See "n key rollover" in google for more details.

That wouldn't solve the problems I was after. But you can now do that using Karabiner Elements on Sierra with the latest build.

I have one and like it a lot, but it doesn't work in my bag or at the coffee shop.

Sure, but Snap and Pop on a keyboard named Crackle? Way more fun.

On the pop layout I have a bunch of keys that are used for shortucts. You could remap any of those to CTRL + ALT + Shift + Insert or whatever other combos you hit often. Also, tying numbers on crackle is as easy as typing capital letters so I don't really miss the dedicated numpad (but no 10 key typing of course).

On this layout "@" is as easy to type as "A"

I just can't stand the idea of walking around with an extra keyboard with my laptop. And the few small keyboards I've tried still don't place all of the special characters in easy to remember places.

I actually got really excited about doing that, but it turns out that apple keyboards are only reliable for a total of 2 simultaneous.

I wanted to keep all of the keys fairly close to the home row. If I do that I can't fit all of them under just snap. It's already full.

Awesome. Let me know what you think after you play with it. I'm totally open to making changes.
