Karabiner
O Karabiner é um aplicativo gratuito de código aberto para customizar o teclado no macOS. Ele pode ser utilizado para re-mapear teclas com pouco uso, como CAPS LOCK ou ⌥-Direita, e transformá-las em algo mais útil, como a combinação ⇧⌃⌥⌘, abrindo inúmeras possibilidades de criar novos atalhos. No meu sistema, por exemplo, ⌥ ← (=⇧⌃⌥⌘←) ativa um macro do Keyboard Maestro que move o aplicativo em primeiro plano para a metade esquerda da tela.
Similarmente…
⌥ →(=⇧⌃⌥⌘→) move para a metade direita.
⌥ ↑(=⇧⌃⌥⌘↑) move para a metade superior.
⌥ ↓(=⇧⌃⌥⌘↓) move para a metade inferior.
A tecla CAPS LOCK, por sua vez, tornou-se F20, que é um atalho para um macro que muda o teclado (pt_BR ⇆ GRC) e ativa o perfil correspondente do Karabiner (você pode criar inúmeros perfis). No perfil para o Grego, transformei a letra u em υ, y em ; e q em θ. Por algum motivo sempre me incomodou o υ ficar na tecla y.
Configurando
Para configurar o Karabiner, você pode utilizar a interface do próprio software, ou editar o arquivo JSON. Se quiser experimentar esse último método, abra o terminal e dê o seguinte comando:
open ~/.config/karabiner/karabiner.json Ou você pode abrir o finder, pressionar ⇧⌘G, colar ~/.config/karabiner/karabiner.json e pressionar enter.
Abaixo transcrevo as minhas configurações. Se você copiar e colar o código terá exatamente as mesmas configurações e funções.
