Scroll the View with Text

With most tools, pressing the Spacebar temporarily gives you the Hand tool so you can navigate in the document. Try that while you're typing and, of course, you get spaces. So how do you do that temporary Hand tool thing when you're typing? Press Command-Spacebar (PC: Alt-Spacebar), the shortcut for the Zoom tool. Once the cursor has changed to the Zoom tool, let go of the Command key (PC: Control key), and you'll have the Hand tool, ready to navigate. Let go and you're right back to typing again.
