Search really fast for files in Eclipse (Java)

ctr+shift+r

For each filename foo two files will be presented:

1. foo.java
2. foo.class

In order foo.class to not be presented right click on it or any folder that it contains it (eg if using Maven right click on folder 'target'), select Properties and click Derived.
