You can enable objects to act as links that viewers tap to jump from one slide to another. This is especially useful when you want to create an interactive presentation that lets viewers choose their own path through the slideshow.
Objects that can be turned into links include shapes, lines, images, image galleries, drawings, text boxes, equations, groups of objects, and animated drawings.
Tap the object you want to turn into a link, then tap Link (you may have to tap 
first).
Choose one of the slide options or tap Link to Slide and specify the number of the slide you want the link to lead to.
To verify the link’s destination, tap 
, then tap Go to Slide.
If you don’t need to verify the link, tap the slide to close the controls.
Linked text is underlined, and a link button (a curved arrow) appears in the lower-right corner of a linked object. (The link button isn’t visible when you play your presentation.)
Tap the link button next to the object, tap Link Settings, then select a different destination.
To remove the link, tap Remove.
To use linked objects to navigate between slides, you must set your slideshow to play as a Normal or Links Only presentation type. You can also set your presentation to play immediately after it’s opened, continuously on a loop, or from the beginning if left idle.
With the presentation open, tap 
in the toolbar, tap Presentation Options, then tap Presentation Type.
Select a presentation type:
Normal: The presentation changes slides or starts animations when the viewer taps or swipes the screen, or taps a link on the slide. This is useful if you want to present slides sequentially.
Links Only: The presentation changes slides or starts animations only when the viewer taps a link on the slide. This is useful if you want to present an interactive slideshow in a kiosk setting, or if you want to present slides in nonsequential order.
Tip: In a Links Only presentation, make sure each slide contains a link (to prevent dead-end slides).
Set any of the playback options:
Loop Slideshow: Turn on to have the presentation return to the first slide at the end of the slideshow.
Restart Show if Idle: Turn on, then drag the slider to set the amount of idle time with no viewer interaction before the presentation returns to the first slide.
Tap Done.
To start the presentation, tap to select the slide you want to begin with in the slide navigator, then tap 
in the toolbar.
