* Adjust TAPPING_TERM to make accessing the nav layer easier * JJ40: Add RESET key to lower layer. * Disable all lock LEDs on "oscillope" keymap. I'm not 100% sure why yet, but attempting to turn on a lock LED on my v1 JJ40 PCB causes the PCB to become unresponsive. The easy fix is to just disable all of the lock LEDs, since I don't have any LEDs on my keyboard anyway. Many thanks to u/wanleg on Reddit for suggesting this fix: https://www.reddit.com/r/olkb/comments/8en8f1/strange_caps_lock_behavior/e06kcaf/
