"The Handout tab is not so much a view as a template for
preparing a hard copy or online summary version of your
presentation. In my experience, handouts tend to be lacking, since
by definition they exclude the details of your talk, and encourage
people to skip the session, but many conferences and individuals
request them all the same.
"From this tab, you can set the number of slides in your
handouts, and the number, position, and size of the slides on each
page from the choices in the Layout tab of the view's task
pane.
"For me, the best layout is the two-column one with slides down
the left and room for brief notes on the right. Strangely, the
notes column does not actually display the notes you enter for each
slide, but you can use the Drawing toolbar to quickly add some text
frames for some brief notes."
