In iOS 7, Apple quietly added new keyboard shortcuts to some of its apps and gave developers the capability to add their own. So if you use a Bluetooth keyboard with your iOS 7 device, be sure to bookmark this list of shortcuts that Federico Viticci is working on. Since there is no official documentation from Apple, Viticci is learning them by trial and error, as well as from reader submissions, and he will update the list as he learns more. follow link
Move to Top Shortcut in iPhone
On an iPhone, flicking all the way back up to the top of a long Web page can be a real drag. Instead, a single tap on the status bar moves you to the top of a page. (The status bar is where the clock is.) This tip also works in other apps, like Mail, Contacts, etc.
