A little known fact about using a Bluetooth keyboard with an iPad (or iPhone) is that keyboard shortcuts within iOS and apps are available. For example, you can open a new tab in Safari on iOS 7 by using
⌘T, the same shortcut used on the Mac.
Federico Viticci at MacStories has created a dedicated section of the site to documenting this increasing number of shortcuts within 3rd-party apps.
System apps like Safari and Mail aren't included on the list though he does link to previous posts covering them in great detail.
If you're an iPad user and regularly make use of a Bluetooth keyboard, keep this page within easy reach.
