...says to find the icon of the pad and pencil:

in the View > Toolbars > Formatting menu. But it's not there. IN addition, the options in the formatting toolbar only become clickable if the cursor is in the text of some topic. I think the directions must be pointing me to the wrong place.

Thanks!
