Some notes from a call with @jackhumbert on chording:

would be good to implement chording as CC_ (instead of KC_). And then a key where CC_ is used would only fire on keyup.

There would be a dictionary under the layout that looks something like:

CC_A && CC_R: LALT(F4) // sends Alt+F4 when you hold down A and R and then let go

If you define CC_S for example but then not define a chord for it, it would just send S on keyup. This way you get consistent behavior in your layout if you want it -- all keys firing on keyup if you want them to.

We would not make a distinction about which key in the chord gets pressed first.

We would support up to 2 keys per individual chord initially.

You'd need to include chording.h to enable this on your layout.

There would be a makefile option to flip this off to save on filesize if needed.
