Macのシステム環境設定から設定できるキーボードショートカットをコマンドラインで設定する方法を紹介します。
他のMacでも同じ設定を追加したい場合などに便利です。
ターミナルからdefaultsコマンドを実行して設定していきます。
アプリケーションごとにKeyが異なり、またアプリケーションごとに動作を確認する必要があるため、全アプリケーション一括で設定ではなく、個別に設定しています。

この設定はアプリケーション再起動後じゃないと反映されないので、ご注意ください。
あと、バックスラッシュを含むショートカットは、バックスラッシュが複数挿入されてしまい、うまくいきません。
なお、新しくアプリケーションを追加したい場合は、システム環境設定からひとつショートカットを追加して、defaults domainsコマンドを用いてアプリケーションのドメイン名を確認します。
（ショートカットを事前に追加する理由は、少なくとも１つはショートカットを設定していないと、ドメイン名が表示されないためです。）
