The quickest way to create a Prototype is to add a Link between two Artboards . You can add Links from any layer to any Artboard.
To add a Link, select a layer, choose next to Prototyping in the Inspector (or press W), then click on an Artboard you’d like to link your layer to.
How to edit Links
In the Inspector, you can choose how a Link’s transition will look using the Animation buttons and change which Artboard a Link takes you to using the Target drop-down menu.
Select “Previous Artboard” in the Target drop-down menu, to tell the Mac app to return to whichever Artboard you were previewing before the current one. This is helpful when you have lots of Links leading to a single Artboard.
How to remove a Link
Choose Prototype > Remove Links from Selection, set your Link’s target to “None” or click the trash icon in the Prototyping section of the Inspector to remove a Link.
