Keynote: make motion path visible
I'm showing a map in Keynote and then want to create a magnifying glass effect on a particular town, using scale and move to create a zoomed-in inset of the town with the whole map still visible underneath (as shown in this demo video: https://www.youtube.com/watch?v=ti_m6ynDVAc)
It all works fine, except I can't find a way to make the motion path visible, so it effectively points to the original location of the town on the map underneath.
Can anyone help?
