你能在这里进行基本的故障排除吗？https://github.com/microsoft/vscode/wiki/Keybinding-Issues,并在侧边栏不可见时发布哪个命令正在执行。我想知道命令是否正确执行。

问题：
打开时具有焦点：

切换侧边栏然后再次打开：

预期结果：
不活动但可见的侧边栏：

File: Focus on Files Explorer 恢复焦点：

尝试使用 workbench.files.action.showActiveFileInExplorer 作为你的命令代替

已经存在这样的快捷键

{
        "key": "ctrl+shift+\\",
        "command": "workbench.files.action.showActiveFileInExplorer",
    },

但是它会将光标移动到当前打开的文件，并且只有在文件资源管理器可见时才会这样做。对于不可见的文件资源管理器，它只会打开文件资源管理器而不显示活动文件，而且只有在打开的文件属于文件树时才会这样做。
此外还尝试了 workbench.explorer.fileView.focus 代替 workbench.files.action.focusFilesExplorer 。它们的行为相同

对于不可见的文件资源管理器，只需打开文件资源管理器而不显示活动文件，并且仅当打开的文件属于文件树时才这样做。
是的，它必须位于文件树中，但是当我将侧边栏最小化时，这个命令对我来说确实可以打开并聚焦文件。然而，您说得对，如果树被隐藏然后揭示，选择就会丢失。这并非所有树的情况，所以我会将其标记为一个错误。
