Hotspots give you more control than Links and are useful if you want to create a clickable area that’s larger than a single Layer.
To add a Hotspot , choose Insert > Hotspot (or press H), then click and drag to draw your Hotspot Area. After that, click the Artboard you want your Hotspot to link to.
You can edit your Hotspot’s animation and target Artboard, in the Inspector, just like you can with Links.
How to turn a Link into a Hotspot
Select any Link and click the “Create Hotspot” icon in the Inspector to turn it into a Hotspot.
How to fix the Position of a Hotspot
Select your Hotspot and then choose the Fix position when scrolling checkbox in the Inspector to fix its position on the canvas even as the rest of your Layers scroll.
How to use Hotspots with Symbols
If you include a Hotspot as part of a Symbol, you can reuse that same Symbol but individually override its Hotspot’s target. You can also override the Hotspot’s target to “None” if you don’t want it to link to another Artboard.
How to hide Links and Hotspots
Choose View > Show Prototyping (or press Ctrl + F) to hide the different paths that represent Prototyping Links and Hotspots. You can also change their color under the Canvas section in Preferences.
