Tip: PDE Tools for ABAP in Eclipse
You can extend your ABAP in Eclipse possibilities with the PDE-Tools. Look here for more information.
My favorites are the Clipboard History and the Crazy Outline view.
With the Clipboard History you can paste the content of the clipboard history, use Ctrl + Shift + V to open an additional window and choose the entry you want.
With the Crazy Outline view you can navigate in your code easily.
