Limelight
Annotate your slides while presenting on a Mac
A live circle or underline makes a slide land harder than words alone. Limelight lets you draw straight over your slides while you present, with no extra setup in your deck.
When you present, you frequently want to mark a slide as you talk — circle a key figure, underline a heading, or connect two ideas with an arrow. Slide apps handle live markup differently, and switching into a built-in pen tool can break your flow and your timing.
Limelight is a menu-bar app that draws over whatever is on screen. With your slides open, press ⌃⌥3 to draw freehand right on the current slide, then press ⌃⌥C to clear it before you move on. Press ⌃⌥3 again to stop drawing and go back to a normal cursor. Your slides keep running normally underneath — Limelight just adds your marks on top.
It works the same over Keynote, PowerPoint, and Google Slides in a browser, and it carries through when you share or project, so a remote audience sees your annotations too. Because it is one consistent tool, you do not relearn a different pen for each app.

FAQ
- Does it work with Keynote, PowerPoint, and Google Slides?
- Yes. Limelight draws on top of your screen, so the same drawing shortcut works over Keynote, PowerPoint, and Google Slides in a browser.
- Will my drawing stay on the slide when I advance?
- Your drawing stays on screen until you clear it. Press ⌃⌥C to wipe it before or after you move to the next slide.
