If you type this example into your VBA Ed itor, you will no tice that the

The next section discusses how VBA can be used to move from one slide to
another. This is an excellent place for a com ment. The VBA command will tell
you that you are moving to slide 3, for ex ample, but it won’t tell you why. If, for
example, slide 3 is your menu, a com ment that says “Returning to the main

with VBA that you al ready can do without it? This is a trick question. While you
can link to the same places with out VBA, your hyperlinks only work when you
click a but ton or text, and linking will be the only thing that but ton or text does.
With VBA, you can link and do something else, or you can link to different
places depending upon the answer to a question (using something like what we
did in Chapter 5 with the
YourName
pro cedure or the
Ques

procedure).
At the end of Chapter 5 you saw the pro cedure
YourNameWithPraise
