8.9.3.1 Configuring jump vs. pop-up hotspots
For a pop-up hotspot, assign property PopOver to the hotspot character format:
Specify PopOver as the first property to the right of the equals sign. Additional properties can follow PopOver; see §8.8.2 Assigning properties to formats for topics and hotspots.
See also §8.9.11.3 Creating alternative pop-ups for an older, alternative way to designate a pop-up hotspot.
For a jump hotspot, you do not have to assign a property to the hotspot character format; jump is the default action for a hotspot.
See also §8.9.11.2 Creating alternative jumps for an older, alternative way to designate a jump hotspot.
When you use a cross reference for a hotspot, make sure the hotspot character format is applied to the reference string (<$paratext>) in the cross-reference definition. If another character format intervenes (for example, if your cross-reference format is defined as <Hotspotfmt><Bold><$paratext></>), the PopOver property is turned off before it can be used.
When you use a hypertext link to designate character-formatted text as a hotspot, do not place any other markers within the hotspot area.
