SandS with Karabiner+Lacaille type thumb shift

When I write a program after changing Japanese input to thumb shift, I want the SandS (space long press and shift key) function.

  • Or rather, my right thumb is on standby on the conversion key, but I don’t need it at all when writing programs, so why not if this is the shift for English letters…?
  • Done The kana key is also the shift key in alphanumeric mode.
  • We won’t talk about this at this time.

• SandS for [karabiner-element

  • https://pqrs.org/osx/karabiner/complex_modifications/#spacebar
  • You can’t do things like alphanumeric mode only, so it clashes with the space key being used as a left shift for thumb shift.
    • Because Lacaille distinguishes between left thumb shift and pinky shift.
  • Then just limit it to alphanumeric mode.
    • I solved the problem by editing ~/.config/karabiner/karabiner.json directly.
