How to enable the bar showing file location in Eclipse

I want to enable the "navigation" bar that is supposed to just below the tabs in the editor. It shows what the file hierarchy is. For example if you had a HelloWorld project it shows: HelloWorld -> src -> SomeClass.java -> main And all the different locations are clickable. I know you can use the double arrows to link what is in the editor to the resource in the package explorer.

Additionally to the shortcut in the answer from Eli, there is a button in your toolbar:

This feature is called breadcrumbs. From Eclipse help:

To enable the breadcrumb invoke Toggle Java Editor Breadcrumb in the toolbar or press Alt+Shift+B in the Java editor.

The enablement of the breadcrumb is remembered for each perspective. The breadcrumb can for example be enabled in the debug perspective and be disabled in the Java perspective.
