SplitKeyboards

So now that I have two 34 key split keyboards on the way I have to start figuring out how to reduce my thumb cluster to only allow for 2 thumb keys per side while still being able to easily access Smart Caps and Smart Numbers.

Keyboards

• Kyria
• Hillside
• On the way => Sweep
• On the way => Dilemma
• Moonlander

Keymap

With the following features:

• Custom layers & layer switching (Only 1 QMK layer, user_layers.c)
• Internally uses custom 8-bit keycodes
• Callum style Oneshot Modifiers (rewrite, oneshot.c, user_oneshot.c)
  • double-tap to lock a modifier
• Smart Numbers (feature.c)
  • will end when pressing space
• Smart Caps (feature.c)
  • holding Smart Caps and repeatedly tapping NAV will cycle:
    • Normal/Repeat -> Camel Case -> Snake Case -> Off
• Smart Caps (feature.c), Normal mode
  • start typing letters
  • will end when pressing space
• Smart Caps (feature.c), Repeat mode
  • first enter some symbols that should be the delimiters
  • then start typing letters
  • space will emit the delimiters (maximum 4)
  • will end when pressing NAV
• Smart Caps (feature.c), Camel Case
  • start with typing letters
  • space will emit a space and set the next letter to be shifted
  • you can use , to activate shift manually
  • tap . to deactivate
• Smart Caps (feature.c), Snake Case
  • start with typing letters
  • space will emit an underscore
  • you can use , to activate shift manually
• SYM key can be tapped for a oneshot key from the SYM layer (feature.c)
  • SYM key can also be held
• RAISE layer can be activated by holding NAV and SYM like tri-layer. (feature.c)
• RAISE layer can also be activated/locked by first tapping SYM then tapping NAV (feature.c)
• Custom leader implementation using NAV as leader key (leader.c, user_leader.c)
  • leader, mode = 1
  • leader leader, mode = 2
  • leader leader leader, mode = 3
  • leader SYM, mode = 4
• Custom normal/shift/ctrl/alt keycodes (cushi.c)
• Custom OS keycodes to deal with Mac OS / Windows / Ubuntu (cukey.c)
• VIM basic features (vim.c)

Leader

The leader key is the same key that activates the NAVIGATION layer (hold), however we treat it as a leader when it is tapped. When it is a single tap the user has 250 ms to tap the first letter in the chain, the letter(s) following are not time bound. Tapping the leader twice means that a second set of chains will be used, entering the chain is not time bound. Then there is also a third set of chains, not time bound, that can be activated by tapping leader three times.

Examples:

Single tap leader chains

• leader f, this will activate easy motion (vscode)
• leader z, this will center the cursor in the middle of the screen (vscode)
• leader d d, this will execute a delete line command
• leader o o, this will execute a insert line below command
• leader g g, this will put the cursor at the top of the document
• leader c i w, this will execute a change inside word command
• etc.. see user_leader.c for the full list

Double tap leader chains

• leader leader n, this will print !=
• leader leader a, this will print &&
• leader leader o, this will print ||
• etc.. see user_leader.c for the full list

Status

• HillSide: OK
• Kyria: OK
• Moonlander: OK

Setup

• Clone the QMK repository and install/setup
• Symlink, see symlink-howto.md

Then compile Kyria, Hillside or Moonlander:

• make splitkb/kyria/rev1:jaykay
• make handwired/hillside/0_1:jaykay
• make moonlander:jaykay
