システム環境設定→キーボード→キーボードショートカットのアプリケーションで、JSONからアプリのショートカットを設定するAppleScript。要JSON Helper

使い方

JSON Helperをインストールする。
更に下記にあるJSONを元に、ショートカットの設定を書き保存する。
下記のソースをAppleScript エディタにコピペし、実行する。
ファイルを選ぶようになるので、保存したJSONファイルを指定する。
あとは無事終わるまで眺める。

環境設定 → セキュリティとプライバシー → プライバシーの「アクセシビリティ」で、スクリプトエディタ.appを許可しておいてください。

JSONを記述する上での注意など

menu

アプリケーションが持つメニュー項目です。一字一句間違わずに入力してください。Sketch 2の一覧はこちらに作成しています→text - Sketch.appのメニュー項目一覧 - Qiita [キータ]

key

後述のmodifier・Fn・return・tabなど以外の文字が打てるキーを指定できます。あと、矢印キーだけは、left / right / up / down で指定できるようにしています。

キーは大文字で指定すると、Shiftキーも併用されていると認識されるので、必ず小文字で！

modifier

command / option / control / shiftです。見てもらったら分かると思いますが、modifierは配列なので同時に押すキーを複数指定できます。

指定する順番は、「command / option / control / shift」の順番です。optionとshiftを指定する場合は、["option", "shift"]です。

その他

10.7.5（Thanks! @nabeoman さん） / 10.8.5 / 10.9 / 10.9.1 / 10.10.1 / 10.10.5 で動作確認しています。

あと、エラー処理などあまり考えてないので、えぇ、自己責任でお願いします。（ソースが酷いのでどなたか指摘していただけるとうれしい…）
