Thanks again to everyone who responded. You guys are the best.
Example:
THIS IS A NOTE WITH
TWO LINES.
Picking anywhere on this note will put a red box around the entire note. Picking again on the note will highlight one of the sections in red. Once a single section is highlighted, you can go to Format>Text Style and change that section only. Doing this would allow the top line to have a different height, slant, underline, etc. than the bottom line.
The next question is how do you do this on a single line?
Example:
THIS NOTE HAS THREE SECTIONS.
You normally enter a note exactly as it looks on the screen. In this case, however, you break up the note and enter as such.
{1:THIS NOTE} {2:HAS} {3:THREE SECTIONS.}
Entering the text like that will allow you to pick the individual sections by themselves, much like the multiple-line first example.
You cannot use this functionality if you try to do the Right Click>Properties button. Indeed, if you highlight a single section and then do a Right Click, you will not see the Properties button, only the Text Style button.
Thanks again,
Don
