Key Shortcut for Eclipse Imports

It's been a while since I last used Eclipse. I used to love this handy key shortcut that added all the imports to the top of the source file, but I've forgotten it. Does anyone know what this shortcut is?

Ctrl + Shift + O (<-- an 'O' not a zero)

Note: This shortcut also removes unused imports.

The above shortcuts are default, if we want to change shortcuts we can do. In eclipse -> Windows -> preferences -> keys. Where we can find all shortcuts with full details:

You also can enable this import as automatic operation. In the properties dialog of your Java projects, enable organize imports via Java Editor - Save Action. After saving your Java files, IDE will do organizing imports, formatting code and so on for you.

IntelliJ just inserts them automagically; no shortcut required. If the class name is ambiguous, it'll show me the list of possibilities to choose from. It reads my mind....
