筆者のmacのノートの（macbook pro 2017)のキーボードのキーは日本語配列になっている．
xquartz内のキーボード入力は，xkbで制御するが，layoutをusに一括変換してくれる方法はみつからなかった．xmodmapを用いて元のレイアウトからusレイアウトになるようにした．
1. xquartz外では，lacailleでusレイアウトの打鍵を実現している．しかし，xquartz内では，lacailleが起動していると，xkbの制御が乱される．lacailleが起動していないと，jisレイアウト
のxkbの制御がうまく動作する．
2. xmodmap -pke > .xmodmaprc_for_usとして，このファイルでxkbのキー設定を変えていく．
また，その前に，xmodmap -pke > .xmodmaprc_asisとして，元のxkbのキー設定を保存しておく．
現在の両者の違いは，
bash-3.2$ diff .xmodmaprc_for_us .xmodmaprc_asis

3. 出来た.xmodmaprc_for_usを読み込む
xmodmap ~/.xmodmaprc_for_us
<2022/9/7 追記 catalinaでクリーンインストールする羽目になり、.xomdmap_for_usのコピーを取るのを忘れており、上記の.xomdmap_asisを手作業で修正した。今後のためにパッチを当てれるようにしておく。
