Keynote trackpad presenter.
A presenter needs three things: next, previous, and a screenshot. Put them on the trackpad and keep the keyboard out of the shot.
When you present, the keyboard is the wrong surface. You are standing, the screen is mirrored, and the one thing you need is a reliable next-slide action.
The Keynote scene puts next and previous on two-finger gestures and a screenshot on a three-finger tap. The corners stay as system actions so you can still reach Mission Control or the desktop.
What the scene does
| Trigger | Action | Source |
|---|---|---|
| Top-left corner | Mission Control | Default |
| Top-right corner | Mute | Default |
| Bottom-left corner | Show Desktop | Default |
| Bottom-right corner | App Switcher | Default |
| Two-finger tap | Next slide | Scene |
| Two-finger swipe left | Previous slide | Scene |
| Two-finger swipe right | Next slide | Scene |
| Three-finger tap | Screenshot | Scene |
| Three-finger swipe up | Mission Control | Default |
| Four-finger tap | Open TrackStudio | Default |
Built-in scene mapping. “Scene” means the app overrides the default; “Default” means the fallback action is used. Check the scene in the app before you edit it.
How to apply it
- Open TrackStudio and select the Keynote scene.
- Check the two-finger gestures: tap or swipe right for the next slide, swipe left for the previous one.
- Keep the top-right corner for mute and the three-finger tap for a screenshot. Test both in presenter mode before the talk.
Where it stops
- No slide picker. The scene moves forward and back; it does not jump to a slide number.
- No presenter notes. Notes stay in Keynote's presenter display.
- No laser pointer. The scene sends slide navigation and screenshots only.
Make the trackpad do more than point.
TrackStudio maps edges, corners, areas, gestures, and haptics to the app in front of you. $5 once. No subscription, no account.

Does this work in Keynote?
Yes. The Keynote scene binds to com.apple.iWork.Keynote and sends next slide, previous slide, screenshot, and mute.
Can I use it in PowerPoint?
Not with the Keynote scene. PowerPoint has a different bundle identifier; add it as a separate scene with the same actions.
Does it work in full-screen presenter mode?
Yes. The actions are the same ones Keynote uses for slide navigation. Test them before the talk because presenter mode can change which window has focus.
Does it need Accessibility permission?
The slide actions use the app's own commands. Accessibility is needed for actions that synthesize keyboard events or move windows.
