Steven Hum of the darnedest thing is configuring the firmware.
Here is a detailed view on what the layout is and why I arranged it that way:
I tried designing the most universally acceptable layout for people who normally use a US QWERTY layout. It includes both the standard number row keys and a numpad. It also has a standard sixkey/nav cluster, Function keys separated into groups of 4 keys, some common one-handed shortcut keys, as well as basic volume/media keys.
Some keys are duplicated to allow for variance in preference, relevant layer convenience, and to allow for more compatibility with software that specifically requires the numpad. Likewise, some typically unused keys are also included for compatibility, such as Scroll Lock and Pause/Break.
Aside from the main qwerty layer, there are four others:
- Orange (right key/right legends)
- Blue (left legends)
- Mixing the two apparently gives this odd greenish hue (bottom sidewall legends)
- Toggle-able Plover mode
- Hold down the Blue modifier key for number row, symbol, a few one-handed shortcuts, and media keys.
- Hold down the Orange modifier key for function keys and the sixkey/nav cluster.
- Hold both color modifiers to access the Greenish color layer: cursor, numpad, and another set of the nav cluster packed around the cursor keys (shown gray on the front sidewalls of the keycaps here).
The enable and disable keys for the steno layer are on different spots so you can be positive you've enabled or disabled it even when you don't remember or aren't sure which mode you are in.
When numlock is turned on (which is found in the Greenish layer), the numpad cluster stays enabled. This allows for one-handed number entry, calculator use, etc., without holding down modifier keys.
Note that the cursor keys are not aligned Vim-style. I'd hope Vim users are savvy enough to modify the configuration to suit themselves. It is also not aligned with the equally familiar WASD. This is because the bottom two rows have larger keycaps than the top row. It feels much more natural for the cursor keys to take advantage of this fact. I think this layout is a good default blend of user-friendly and comfortable.
