I've used hidden text to do many different things for people, but here is one of my favorite applications. I have a client who often serves as an expert witness at trials. He used to create two totally different documents. When it comes time to print, he prints one copy without the hidden text showing and one copy with. Work With Tables in Outline View.
Tables are a great way to organize information.
However, they are not always easy to rearrange once they're created. Most people rearrange rows in a table by selecting the row, cutting it, and then pasting it where they want it to go. It is also subject to error because selecting just the right thing with a mouse can be tricky. Each table row is displayed as a separate paragraph in the outline, complete with the outline bullet to the left of the margin. Drag the bullet to move the row around.
