求助：Cursor IDE中无法移除的deleteWordLeft快捷键异常问题

从某个未知时间点开始，在与VS Code并排安装的Cursor IDE中按下Ctrl+Backspace时，即便焦点处于查找框、全局搜索框、命令面板或其他任何可聚焦区域，都会删除文本编辑器中的单词。

在键盘快捷键菜单（Ctrl+K Ctrl+S）中排查后发现，存在一个无任何触发条件的deleteWordLeft命令绑定，配置如下：

{"key": "ctrl+backspace", "command": "deleteWordLeft"}

该绑定显示为用户自定义配置，无法通过UI移除、修改或重置（重置操作仅会新增一个带标准条件的快捷键，但原绑定并未被删除），也无法被其他命令覆盖。

• 清理Cursor缓存
• 打开其他文件夹测试
• 通过extension bisect禁用所有扩展
• 进行键盘快捷键故障排查，确认触发的确实是该无条件绑定，日志如下：

• 直接删除异常绑定

  1. 按下Ctrl+Shift+P唤起命令面板，输入Preferences: Open Keyboard Shortcuts (JSON)并执行，打开用户快捷键配置文件。
  2. 在文件中定位到{"key": "ctrl+backspace", "command": "deleteWordLeft"}这一行，直接删除该条目。
  3. 保存文件（Ctrl+S），重启Cursor后即可恢复Ctrl+Backspace的标准功能——仅在文本编辑器聚焦且可编辑时删除左侧单词，其他输入区域正常执行对应删除操作。

• 若无法找到异常绑定，添加覆盖配置
  如果在JSON配置文件中找不到上述异常条目，可手动添加以下配置来覆盖全局绑定：

  // 禁用无约束的deleteWordLeft绑定
  {
    "key": "ctrl+backspace",
    "command": "-deleteWordLeft"
  },
  // 添加标准条件的正确绑定
  {
    "key": "ctrl+backspace",
    "command": "deleteWordLeft",
    "when": "editorTextFocus && !editorReadonly"
  }
  

  保存文件并重启Cursor即可生效。
