As a new generation of touch- and pen-enabled devices enter our world, you may find yourself wanting to use your pen to annotate and comment on documents or illustrate ideas in Word, Excel, or PowerPoint.
While static ink can be useful, the ability to replay those ink strokes as they were drawn lets you illustrate things step by step, or show a thought process. You can hide and reveal content on your slides or emphasize individual elements in a group or series. You can see the order in which ink was drawn, pause the replay, and select the point to start the replay from.

Using Ink Replay
When you use your stylus or touch screen device to draw ink on a page, the Ink Replay option becomes available on the Draw tab of the Ribbon to rewind and replay your ink strokes as they occurred.
Make Ink Replay visible on the Ribbon
Ink Replay was mistakenly hidden from view for some users of PowerPoint 2016 on devices that aren't touch-enabled. This mistake has been corrected in version 16.0.8112. If your PowerPoint has been affected, once you have version 16.0.8112 or later installed, you can permanently correct the problem by resetting the customizations for the Draw tab, as follows:
Open File > Options.
Select the Customize Ribbon tab in the Options dialog box.
In the box on the right side of the dialog box, ensure that the Customize the Ribbon box is set to Main Tabs or All Tabs.
In the long box below that, select the entry for the Draw tab.
At the bottom of the dialog box, open the list box named Reset and select Reset only selected Ribbon tab.
Click OK to close the dialog box.
The Ink Replay button is now restored to the Draw tab.
