なぜLCtrl + LeftとLShift + Leftだけが機能しないのですか？

Linux（Kali）で最近奇妙な動作が発生しました（以前は気づかなかった）。

RCtrl+Right Arrow操作
RCtrl+Left Arrow操作
RShift+Right Arrow操作
RShift+Left Arrow操作
LCtrl+Right Arrow操作
LCtrl+Left Arrow 動作しません
LShift+Right Arrow操作
LShift+Left Arrow 動作しません
RCtrl+ RShift+Right操作（次の単語を選択）
LCtrl+ RShift+Right操作(同じ)
LCtrl+ RShift+Left 動作しません
LCtrl+ LShift+Left 動作しません

LCtrl したがって、/ LShift+の組み合わせLeft arrowを除くすべてのキー入力が正しく機能しているようです。

なぜこのような奇妙な動作が発生するのかご存知ですか？

予想される行動と調査の更新：

LCtrl私は+が+と同じように（または+と同様に）動作したいと思いますLeft arrow。カーソルを前の単語に移動する必要があります。私たちは友達ともう少し調べたところ、同じ設定の外部キーボードを使用することが期待どおりに機能するようです（前の単語に移動するには2つのキー+左矢印）。したがって、これが最初のハードウェアキーボード（ノートブックキーボード）。RCtrlLeft arrowLCtrlRight arrowCtrl

この問題に対する「ハードウェア」の修正に関する提案はありますか（Linuxとは関係がないため、正しいStack Exchangeサイトではない可能性があります）。

簡単に言うと、Left arrow同時に押すとright arrow（どちらの場合もLCtrl + LShift）、いくつかのイベントが生成されるようです。

なぜLCtrl + LeftとLShift + Leftだけが機能しないのですか？
