If you use a real keyboard with the iPad, the arrow keys work...![]()
Even at that, though, not being able to position the cursor with a mouse and drag to select text, then using the key combination commands (command-C, etc), makes editing text on the iPad a bit of a slog for me. Not that I can't or don't do it (I'm typing this on my iPad right now), but I don't find the touch screen text selection process nearly as streamlined as using a keyboard and mouse to select and manipulate text. It works on the iPad, but if it was my only option I'd go mad in short order if I had a lot of text to edit.
