Specify details for the destination:
Open a presentation, then choose Keynote > Settings (from the Keynote menu at the top of your screen).
Click Auto-Correction at the top of the settings window.
In the Formatting section, do any of the following:
Website URLs and email addresses: Select or deselect the “Automatically add links to webpages and emails” checkbox.
Phone numbers: Select or deselect the “Automatically add links to phone numbers” checkbox.
If you don’t want links to show formatting but you still want them to be active, select “Automatically add links to webpages and emails” or “Automatically add links to phone numbers” and deselect “Automatically apply link style.”
The setting applies to new text that you enter in all Keynote presentations. Existing links aren’t affected by the change.
You can set up your slideshow to be an interactive presentation that changes slides when the viewer clicks its links. An interactive, links-only presentation is especially useful in a kiosk setting.
