Nanoraptormore keyboards should have obtuse parts. things that aren't needed. switches that will never be touched.
num lock. static lock. try. try not. F15. unpipe and unpipe 2.

@NanoRaptor. the best part of an oversized custom keyboard is figuring out how to bind and label all the surplus keys.
I have had "Less Rawr" (media stop), "Attack 0" (programmable macro), "Button 4" (emulates mouse button 4), and "憎恨" (shifts to altrrnate bindings) keys
