HOW TO Add a video to a slide

1 Build a new gesture

Select Global on the left and click Add New Gesture. In the Touchpad Gesture pop–up, choose Five And More Finger Gestures > 5 Finger Swipe Left. In Predefined Action, choose Window Resize & Move > Maximize Window Left.

2 Test your gesture

Switch to Finder and open a new window, then perform your gesture. The window should immediately snap to the left half of the display. (Note: some apps have minimum window widths, which may take up over half of small displays.)

3 Practice gestures

If you find it hard to consistently trigger a gesture, click Show Live View (bottom–left). The new window shows the positions of your fingers on the trackpad. Perform gestures, and it’ll say the action they would have triggered.
