I would like to highlight some imperatives during an upcoming sermon during the actual sermon and then have the ability to remove the highlight quickly. I was watching a YouTube vide of Mark Winger do this, but cannot replicate it. I can highlight by clicking and dragging and then hit a shortcut key, but Mark seems to just drag and it highlights as he drags. I only have all the features of L8--but not L9 if that makes any difference. For instance, I do not have Canvas (maybe that is where Mark does it.) I have tried a number of options but nothing seems to work. (For instance, I pressed F8 to Draw on Screen, but the little yellow dot I get to do that is too small for me to find quickly in the midst of a sermon. Any help? Thanks in advance.
