While editing, you switched to another editor to make sure that you had the name of a variable right. But you have 15 editors open . How do you get back to the exact line of code you were editing?
2.7.2 Solution
Select Navigate Go to Last Edit Location (Ctrl-Q), which moves you back to the location where you last made a change in an editor. You'll also see a button for this function in the toolbar when working with editors.

Eclipse lets you easily move between edit locations, a valuable addition to any programmer's toolset. If you can't see these buttons in your current perspective, you might need to add them by selecting Window Customize Perspective Other Editor Navigation).
