I am doing the synchronization for slide 5 in the workspace. How can I mark its start and end points in the audio?
Select Slide 5 in the slide selector by clicking on it. You will notice two blue markers in the workspace, one saying Slide 5 begin and the other saying “slide 5 end”. Drag these markers to appropriate position in the audio and the slides will get marked. Change the position of the markers as often as you want. Note that marking the end of Slide 5 also marks beginning of Slide 6. Similarly marking beginning of Slide 5 also marks end of Slide 4.
