In Eclipse you can check the "Link with Editor" option and whatever source file you are viewing in the current tab will be highlighted and have its package expanded in the Package Explorer view.
Is there something equivalent to this in IntelliJ IDEA 8.1?
Update (2020, eleven years later): see "Source code navigation / Locate a file in the Project tool window"
In the
Project
tool window, right-click theProject
toolbar and, from the context menu, selectAlways Select Opened File
.After that IntelliJ IDEA will track the file that is currently opened in the active editor tab and locate it in the
Project
tool window automatically.
Original answer (2009)
That would be : Autoscroll from Source.
Navigate from a file in the Editor that gets the focus, to the corresponding node in the Project Tool Window.
Fried Hoeben comments that
you get there from the config of the project tool window.
It is not present in the general IDE settings (at least in version 12)
