title: How to enable the bar showing file location in Eclipse
body: <p>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.</p>
