return to home screen on emulator

How do I return to Android's home screen on the emulator from anywhere? The home key does not seem to work. I am using Android 2.1.

EDIT: It is working when I use the sdk but when I compile from the AOSP sources (version 2.1) it does not work. Perhaps someone encountered this prob开发者_高级运维lem.

Use the Escape key.

(Why the answer should be bigger than 30 chars?)
