You can apply a single type of transition to all slides in the presentation
or apply a different transition to any single slide, even having a
different transition for every slide in the show. While using many
different transitions may be fun to do, it may not give your show a
professional appearance.
Tip
If you want most of the slides to have the same transition, but a
few to be different, you may find it easier to apply one transition
to all slides and then change only the ones you want to be
different.
Setting the timing of automatic slide changes
You can set up a slide show to run automatically, either unattended or
while you speak. To set the default time for slides to be displayed
before changing to the next slide, go to the Slide Transition drawer of
the Tasks pane (Figure 171), leave the transition effect set to No
Transition, choose Automatically after in the Advance slide section,
set a time, and click the Apply to All Slides button.
To vary the timing for some slides, choose Slide Show > Rehearse
Timings from the menu bar, or click the Rehearse Timings icon on
the Slide Show toolbar. The slide show begins in full-screen mode, and
a timer appears in the lower left-hand corner of the screen.
When you want to advance to the next slide, click the timer. To keep
the default setting for this slide, click the slide, not the timer. Continue
for all slides in your presentation. Impress records the display time for
each slide. When you next look at the time set under Automatically
after, you will see that the times have changed to match what you set
when rehearsing.
If you want the whole presentation to auto-repeat, open the menu
Slide Show > Slide Show Settings. Click Auto and OK.
Playing a sound throughout the presentation
You can use the Slide Transition pane to set up Impress so that a sound
or a song is played throughout the presentation. To do that:
1) Select the slide where you want the sound to start and go to the
Slide Transition pane.
2) In the Modify transition section, select the entry Other sound
from the Sound drop-down menu.
