What is Screen Markup?
Screen markup is the practice of overlaying visual marks, such as highlights, circles, or sketches, on your display to draw attention to specific parts.
Screen markup is a broad term for putting visual marks on what is shown so others understand what you mean. It covers everything from drawing on a captured screenshot to sketching live over a running app. The shared idea is that the marks sit on top of the content and direct the viewer to a specific spot.
Markup splits into two modes. Static markup annotates a frozen image and is often saved and shared as a file. Live markup happens in real time over your actual screen and is usually cleared afterward. Choosing between them depends on whether you are documenting something or presenting it in the moment.
Limelight handles the live side on macOS as a menu-bar overlay. You draw freehand markup over any app with a hotkey and wipe it with ⌃⌥C. Because it is a pure overlay running alongside your recorder or meeting app, your markup appears in the recording or call without altering or saving the underlying content.

FAQ
- Is screen markup only for screenshots?
- No. Screenshot markup is one form. Live screen markup, like Limelight, draws over your running screen in real time during demos and calls.
- Does Limelight markup change the app underneath?
- No. It is a transparent overlay. The app beneath is untouched, and the marks clear with ⌃⌥C.
