QMK HHKB Keymap: blakedietz

This is my (Blake Dietz's) own take on a QMK keymap for the Happy Hacking Keyboard Pro 2 alternate controller made by Hasu. A lot of the functionality was inspired by the ergodox ez default layout.

Dependencies

macOS

brew tap osx-cross/avr
brew install avr-libc
brew install dfu-programmer

Windows/Linux

Build Environment Setup

Flashing

You will need to make sure that you have something that you can use to press the button on the alternate controller in order to put it into boot mode.

From the hhkb directory run the following:

make clean
make hhkb:blakedietz:dfu

Press the button on the alternate controller to put the board into boot mode.

You'll see an output similar to the following:

make hhkb:blakedietz:dfu

Making hhkb with keymap blakedietz and target dfu

Layers

Default

A more "standard" layout

This layout places tilde in the standard location. Backspace is moved to the two upper-right-most keys and pipe is put back where it belongs (where backspace is on the default hhkb2 keymapping).

Hyper key

This layout throws out the HHKB's control key in favor of a Hyper key. Ctrl is instead placed on the z and / keys and can be activated with a long press. I find that this is far more ergonomic as it's less of a reach and it allows you to alternate to either hand when you need to use ctrl as a modifier.

The hyper key can be held for hyper and tapped for escape. You'll find that this is quite nice for vim.

Enter is also a hyper key. This allows for symmetry between control and enter. Hold for hyper, tap for enter.

Tap to Hold
CTL, ALT, GUI

Since the HHKB does not have three super/meta keys, these keys were moved to pinky, ring and middle finger for ctrl, alt/ option and super respectively. This is closer to home row which I've found causes less strain.

The Alt and Super keys are instead replaced with layer toggle keys to go to dev and mouse mode respectively.

Space

Hold space to switch to dev mode. This will put you on a layer to have vim like arrow functionality on h,j,k and l. Use this in editors that don't have vim keybindings.

Dev

The Dev layer can be activated holding space or hitting the HHKB's Alt key. This will put you in a mode where all function keys are available and left, right, up and down are mapped to their vim equivalents. The function keys are mapped in such a way that you can use them for debugging. Typically I map debugging functions in all IDEs to the following for a seamless debugging experience (e.g. jumping from Intellij to chrome dev tools and back):

  • f1 -> step over
  • f2 -> step into
  • f3 -> step out
  • f4 -> continue
  • f5 -> set break point on current line

Media

The media layer can be activated by pressing and holding the semi-colon. I've also placed the play and pause key on the apostrophe key in the media layer. This allows you to easily roll your pinky from the media toggle (semi-colon) to the play/pause key in one fluid motion.

I've also tried to logically map next/previous track along with volume up/down vim behavior. In vim since middle finger goes up on k and index finger goes down on j, next/prev track is k/j respectively. ,/m changes volume up/down respectively while toggled to the media layer.
