Here’s a little gem for those who want to move around a large document using the Navigator palette.
You can use the shortcuts Space+Apple and Alt+Space+Apple to zoom in and out of your document in the Navigator palette - they are not for use just in your document view! This is great when you are working on a very large document, but remember that the Navigator palette does steal valuable processing cycles, so it may not always be appropriate to use the Navigator palette on very complex documents if you are using quite a slow computer.
