 Craft a Linking Book from a vanilla book and an ender pearl, then use it in the
 air. An unbound book opens a screen where it can be named and bound to the
-current location. A bound book opens its destination screen and travels only
-when the Link button is pressed. The destination is stored on the item and
+current location. A bound book opens its destination screen and travels when
+its preview panel is clicked. The destination is stored on the item and
 survives inventory and world saves. Travel only succeeds if the target
 dimension is loaded and a solid, collision-free landing position can be found
 nearby.
