Using an iPad with a hard keyboard is kinda nifty. There’s Cmd+Tab to switch between apps, Cmd+Space to search. Arrow keys, with the Cmd and Alt modifiers work as they should. And while i’ve been searching for a Back button on the iPad, you can go Home using the keyboard with the shortcut Cmd+H. Nifty.
Coming from an Android world, a universal Back button is a central navigation device that i’m truly missing.
