Some fix (Backup recommended)
- 26.4.4でもVNCなどではうまく動作しないという報告があったのでキー入力設定画面でAltを押しながらのキーで警告音が鳴るのは仕様ということで諦めてAltGrを優先することにした (#541, #913)
- Due to reports that it still does not work correctly in environments like VNC even in 26.4.4, the warning beep when pressing keys with Alt in the key configuration screen is now treated as expected behavior, and AltGr is prioritized. (#541, #913)
