QMK Extensions for Hobbyist Stenoboards

Longtime steno friend and community contributor Joshua has just released a package of extensions to QMK (the popular open source mechanical keyboard firmware) that enables first-up chord-send and tap-and-hold chord repeat extensions, compatible with the Planck, Preonic, ErgoDox EZ, Clueboard, Cluepad, and Atreus. Handy stuff for people who want to be able to send repeated navigation commands via their steno machine without having to press and release for each one. Nice work!
