Just discovered this feature on my Samsung Galaxy S – if you hold down the menu button on pretty much any screen (worked on all ive tried except the Wireless AP settings screen), Android will go straight to a ‘Quick Search’ mode allowing you to search your phone, internet, etc at a touch. This is great since it saves me browsing through apps, contacts, etc and is similar to the awesome Windows search feature ive come to love in Vista and Windows 7.
More than likely every other Android user on the planet knows about this feature and if i had read the Android manual it would probably have been on page 1 …
