Menu just does what menu always has, pulls up the equivalent of the right-click menu with a single press. I guess I could repurpose it for Copilot, LOL.

I like to make these boards with short keys both to pack more buttons in, and so none of them need stabilizer assemblies, which add complexity and have to be "just so" to work without negatively affecting sound or feel. I've also discovered "Hold-Tap" functionality, which I'm using on the bottom row. The two mini-space bars, plus Function and Right Alt are all spacebars if you tap them, but the Fn and RAlt do their labeled job if I hold them down. Even just making them all a touch bigger than normal (i.e. "1.25 units") is good enough to keep me from hitting more than one at a time.
