So, I do not know the answer to this, but I believe this is something new in the PowerPoint animation options!
Maybe the better question to start with is, does anyone recall if the IN SLIGHTLY and OUT SLIGHTLY effect options to the BASIC ZOOM animation have been there?
I do not recall these options being available and have long used a combination animation of a Zoom + Fade to create the effect (Tip: use the Brightslide PPT add-in “My Animations” to create a quick to apply library of custom animations!). I also reached out to Steve Rindsberg and sent him the above screen capture. He looked in a few legacy installs of PowerPoint and commented that the In Slightly and Out Slightly effect options were not there. So… is this an exciting new addition, or something I just cannot remember was there?
