Here’s another quick tip from my eBook iPad Academy: Tips, Tricks & Clever Techniques. I uploaded new versions of the book today in PDF and ePub format.
Adding an external Bluetooth keyboard (General > Bluetooth) or USB keyboard (may work with the Camera Connection Kit) gives you access to common keyboard commands such as Copy (Command-C) and Paste (Command-V). You also have additional options for selecting text, using the arrow keys for navigation, and deleting words (Option-Delete) or entire lines (Command-Delete). Press Command-Up arrow to jump to the top of a document (like a Home key), or Command-Down arrow to jump to the end (like an End key).
