US親指シフト：MacのUSキーボードで快適に親指シフト入力するスマートな方法(2018/7改訂版)を公開しました。(2018/07/19)
MacOS Sierra(10.12)以降に対応したKarabiner Elementsで利用できる方法ですので、ぜひお試しください。

以下、旧OS用の方法として継続公開します。

本稿の方法はOS X El Capitan 10.11.6 までで動作確認済み。
Karabinerは現時点(2016/11/04)でMacOS Sierra(10.12)未対応のため利用できません。

前回のエントリーからの流れで、
MacのUSキーボードでも快適にorzレイアウトの親指シフト入力ができるように、Karabiner(Mac用キーボード置き換えソフト)の設定を詰めてみました。

右手ホームポジションの移動に慣れるまでは少しイライラしましたが、一度慣れてしまえばこれが最強と思われます。

orzレイアウトのメリット

orzレイアウトは↓こんな感じのキーボード配列です。
左親指シフトキー→スペースキー、右親指シフトキー→右コマンドキーに割り当てて使うのがふつうです。
不自然に右手の親指を曲げる必要がなくなるのが最大のメリットです。

orzレイアウトのデメリット

USキーボードでは「ぉ」(ちいさい「お」)に相当するキーが存在しないので、どこか他のキーに割り当てなおす必要がある
英語モードと日本語モードで右手のホームポジションがずれるため、日本語入力ソフトの文節操作やキーボードショートカットで混乱することが多い

こんなふうにしてみた

「ぉ」は「ぇ」の右隣りに移動した
ctrl shift command と組み合わせて右手のアルファベットを打鍵する場合に、キートップの印字通りの文字を入力するか、ひとつずらして入力するかをオプションでそれぞれ選べるようにした
右にずれて使わなくなったY H N はオプションで無効化できるようにした

設定ファイルとインストール方法

(1) 次の3つのテキストファイルを追加する

/Users/ユーザ名/Library/Application Support/Karabiner/uso/usorz_base.xml
・・・親指シフトキーにどのキーを使用するか定義

/Users/ユーザ名/Library/Application Support/Karabiner/uso/usorz_main.xml
・・・日本語モードでの各キーの割り当てテープル

port/Karabiner/uso/usorz_modkey.xml
・・・日本語モードでのctrl,shift,command+右手各キーの割り当てテープル

(2) Karabinerの設定ファイル(private.xml)を以下のように編集する

private.xml(例)

<?xml version="1.0"?>
<root>

  <item>
        <name>hoge1</name>
        ・・・・・・・・・・・・・・
        ・・・・・・・・・・・・・・
  </item>

  <item>
        <name>hoge2</name>
        ・・・・・・・・・・・・・・
        ・・・・・・・・・・・・・・
  </item>

===↓ この下4行を追加する
  <item>
        <name>US親指シフト入力</name>
        <include path="uso/usorz_base.xml" />
  </item>
===↑

</root>

(3) Karabinerの設定ダイアログでReload XMLボタンを押して設定内容を反映させる
