I'm using Camtasia 9. I entered a } in a blank text box. When I enlarged it to the max, it was still not big enough. Consider adding curly braces and square brackets and angle brackets (< >) under Animations for quicker access. This would save the trouble of having to use a blank text box, then trying to format it. Not only that, the } in the blank text box does not take up most of the text box so it doesn't scale that well when I enlarged it.
I was using the } to identify a group of rows on an Excel spreadsheet. While thinking about the curly braces, I also decided that square brackets and angle brackets might be of use to others.
