The image above is a good fried of mine. It helped me a lot while writing my thesis. I ended up using FrameMaker and learned to appreciate the zooming function. With a few Cmd-Minus strikes it was possible to zoom out to see the entire document with plenty of pages as little thumbnails. Click somewhere else to set the cursor, and Cmd-Plus-Plus-Plus set the scale back to 100% to continue writing on another section.
There was just one problem: little stamp size images of pages all look the same! How to tell which is which? Therefore I placed the image of the scratched paper on the pages where I wanted to continue writing. Thanks to these visual cues it was possible to spot the areas in progress while looking at my document from a bird’s eye view.
