This repository hosts the reverse-engineered and modded firmware for the Truly Ergonomic keyboard.

Added features:

• Table-based Fn and Num Lock layers, customizable independently of the main layer, for both PC and Mac layouts.
• Up to 23 different media/application launch/application control keys (limit raised from original 13).
• Media keys no longer confined to the Fn layer.
• Non-synchronized Num Lock no longer tied to the status of the LED. If you press a Num Lock-sensitive key and your OS Num Lock is off, the firmware will turn it on first and back off when you stop typing.
• Visual web-based configurator.

Removed features:

• DIP switch–based key translation: Henkan→Delete, Apps→Space, Euro2→Yen.

Known problems:

• Non-synchronized Num Lock may be too invasive — it does not provide an easy way to press an affected key without Num Lock turning on. Meaning you can’t play games that expect you to use keypad in arrows mode.
• You cannot easily turn on MouseKeys (typically [Alt+]Shift+Num Lock). If you do inadvertently turn it on, you cannot easily turn it off. (You might work around this by configuring one of the keys as a real Num Lock.)
