There is a button in the Package Explorer view that looks like two yellow arrows pointed at left and right. The tooltip is "Link with Editor". Click that.
Package Explorer 视图中有一个按钮，看起来像两个指向左右的黄色箭头。工具提示是“与编辑器链接”。单击那个。

I've found that constantly syncing package explorer with editor causes package explorer view eventually to grow too long, especially with large projects. I've instead mapped a keyboard shortcut to sync package explorer with the editor. If you are using mylyn this is of course a smaller problem.
我发现不断将包浏览器与编辑器同步会导致包浏览器视图最终变得太长，尤其是对于大型项目。我已经映射了一个键盘快捷键以将包浏览器与编辑器同步。如果您使用的是 mylyn，这当然是一个较小的问题。
Key mappings are available at Window -> Preferences -> General -> Keys -> Show In (Show In Target Id: Package Explorer). Mine is ctrl-alt-left arrow, be welcome to copy.
键映射可在Window -> Preferences -> General -> Keys -> Show In (Show In Target Id: Package Explorer)。我的是ctrl-alt-left arrow，欢迎复制。
Edit: In Luna Command name has changed a little. Instead of Show In (Show In Target Id: Package Explorer)command is now Show In (Package Explorer).
编辑：在 Luna Command 中，名称发生了一些变化。而不是Show In (Show In Target Id: Package Explorer)命令现在Show In (Package Explorer)。

How to use Show In functionality from the popup menu
如何使用弹出菜单中的 Show In 功能
Press Alt+Shift+Wwhile you're in an editor. This pops up a menu with a number of choices. The choices will vary depending on what plugins you have installed. Select the option you want and press Enter.
按Alt+ Shift+ W，而你在编辑器中。这会弹出一个包含多个选项的菜单。选择将根据您安装的插件而有所不同。选择您想要的选项并按Enter。
The fastest way to select an option is to use the first letter of the option, eg. to go to the Package Explorer, press P(you may have to do this 2 or 3 times depending on how many other options start with P). The press Enter. You could also use the arrow keys.
选择选项的最快方法是使用选项的第一个字母，例如。要转到包资源管理器，请按P（您可能需要执行此操作 2 或 3 次，具体取决于有多少其他选项以 P 开头）。新闻界Enter。您也可以使用箭头键。
Invoke "Show In" faster with a keyboard shortcut
使用键盘快捷键更快地调用“Show In”
If you frequently use one of the options (eg. Package Explorer), you can map a single keyboard shortcut to invoke it.
如果您经常使用其中一个选项（例如 Package Explorer），您可以映射单个键盘快捷键来调用它。
- Go to Windows > Preferences > General > Keys.
- Search for Show In. Eclipse will list a number of Show In options. In our case we want Show In (Show In Target Id: Package Explorer).
- Select the command you want, enter a key in Binding and you're done.
- 转到 Windows > 首选项 > 常规 > 键。
- 搜索显示。Eclipse 将列出许多 Show In 选项。在我们的例子中，我们想要 Show In（Show In Target Id: Package Explorer）。
- 选择你想要的命令，在绑定中输入一个键，你就完成了。
