In Eclipse Juno, if I edit the Java file in the advanced Java editor and run unit test, the JUnit View will appear in a floating window.

The Java editor remains active, and JUnit View hides half of my screen. How can I hide a JUnit window using keyboard shortcuts?
I used Juno Service Release 1, Build id: 20121004-1855, and it is the same with Juno Service Release 2, Build id: 20130225-0426.
