How do I use the "comments" functionality during a slide show?

[GFitting]

I need to use the functionality that the reviwer "comments" provides during
the slide show. The "comments" icon is not viewable during the slide show.
How can this be accomplished?

You could try the following instead:
During the show, right click on the slide
a context menu will appear
go to screen>>>speakers notes
then type in the info or comment that you want
Hope this helps!!!
