Here’s a neat and (I believe) completely unintentional feature of Eclipse…
If you’ve added your projects to SCM through Eclipse, it will mark changed files (and directories containing changed files) with an arrow (a “greater-than” sign) in the Navigator and Package Explorer. If you want to quickly flip through the changed folders and files, put focus into the view and hit the “greater-than” sign.
Of course, there is a downside as discussed in bug# 116901.
