KeyRemap4MacBook

Macでキーマップのカスタマイズと言えばKeyRemap4MacBook(とPCKeyboardHack)。以前(もう1年近く前!)同じようにカーネルに潜り込んでキーマップをカスタマイズするドライバを作ろうとしたことがあったのですが、私にはちょっとムリだったようで…。個人的にはsysctlで設定を変更できるインターフェイスが秀逸だなぁと思っています。

そんなKeyRemap4MacBookですが、ちょっとパッチを当てて使っています。アプリケーションキー → F11、Command R → Option L のマップを追加しているのと、キーリピート周りを少し変えています。
