For Chrysalis presentations you can include links - internal ones to other slides in the presentation or external ones to resource files, websites, other URLs, etc. - and set them to be created as a button in the output, rather than the normal clickable words. For example:
An icon is added to the end of the link button to indicate the type of link - an external link (first button) or internal link (second button).
The colour of the buttons is set in the theme.
