Does NetBeans have any "collapse all" shortcut for open directories in the navigator view?
提问by Steve Perkins
NetBeans has a helpful (to meanyway!) feature under the "Views" menu, called "Synchronize Editor with Views". As the name suggests, toggling this on will cause the navigator view to jump straight to a file when it's opened in the editor.
NetBeans在“视图”菜单下有一个有用的（无论如何对我来说！）功能，称为“将编辑器与视图同步”。顾名思义，打开此选项将导致导航器视图在编辑器中打开时直接跳转到文件。
I generally prefer this to the normal "Ctrl+Shift+1" shortcut for manually jumping to a file. However, the downside is that after editing several files, your navigator tree is a mess of multiple open directories.
与手动跳转到文件的普通“Ctrl+Shift+1”快捷方式相比，我通常更喜欢这个。但是，缺点是在编辑多个文件后，您的导航树是多个打开的目录的混乱。
Eclipse has similar functionality, but it alsohas a "collapse all" button at the top of its navigator view... restoring things with a single click having to scroll around. Does NetBeans have any similar mechanism for collapsing open directories? Maybe a poorly-documented keyboard shortcut buried in there or something?
Eclipse 具有类似的功能，但它的导航器视图顶部也有一个“全部折叠”按钮……只需单击一下即可恢复内容，必须滚动浏览。NetBeans 是否有任何类似的折叠打开目录的机制？也许是隐藏在那里的记录不完整的键盘快捷键或其他什么？

Unfortunately, after further digging on the NetBeans discussion forums and mailing lists, it seems that this functionality simply doesn't exist. That's a shame... hopefully they'll add it in the future.
不幸的是，在深入研究 NetBeans 论坛和邮件列表之后，似乎根本不存在此功能。真可惜……希望他们将来会添加它。

A dirty solution is to close the project and reopen it. It will start collapsed.
一个肮脏的解决方案是关闭项目并重新打开它。它会开始崩溃。

Close the navigator (press the x). Then go to Window->Navigating->Navigator or press Ctrl+7. It should open the navigator with all collapsed.
关闭导航器（按 x）。然后转到 Window->Navigating->Navigator 或按 Ctrl+7。它应该打开所有折叠的导航器。
