What Is Region Spotlight?
Region spotlight is a screen recording effect that dims the area outside a defined rectangle, leaving only the highlighted region at full brightness and drawing the viewer's eye directly to the content that matters.
Region spotlight is a focus technique that works through contrast: by reducing the visual weight of everything outside the target area, it makes the target area demand the viewer's attention without requiring any physical zoom or scale change. The full screen remains visible and provides context — the viewer can see that the spotlight region is a panel inside a larger interface — but the dimmed surroundings no longer compete for attention. This is particularly useful for pointing out a specific section of a large, information-dense UI, such as a particular column in a wide table, a settings panel nested inside a complex preferences window, or a specific pane in a split-view editor.
The implementation of region spotlight requires a semi-transparent dark overlay applied to the full screen with a rectangular cutout at the focus region. The cutout should have either a sharp edge (for precise callouts of small UI elements) or a soft feathered edge (for a more natural vignette effect). The darkness of the dim layer should be calibrated to make the spotlight visually dominant without making the surrounding content completely illegible — typically 50–70% black opacity works well across a range of screen contents. The spotlight region should be resizable and repositionable during the recording session, allowing the presenter to shift focus dynamically.
In Limelight, region spotlight is activated with ⌃⌥4. The presenter can drag a rectangle over the area to focus, and the surrounding screen dims immediately. The spotlight region can be moved and resized in real time during the recording, allowing focus to shift across different parts of the screen without cutting away or zooming. This makes region spotlight especially useful for dashboard tours, settings walkthroughs, and any workflow where the presenter wants to guide attention through multiple areas of a complex interface in sequence, maintaining full-screen context throughout.
Why Limelight

FAQ
- How do I activate region spotlight in Limelight?
- Press ⌃⌥4 (Control-Option-4) to enter region spotlight mode. Drag a rectangle over the area you want to highlight. The surrounding screen dims immediately. Press ⌃⌥4 again to remove the spotlight.
- Can I use region spotlight and auto-zoom at the same time?
- Yes. Region spotlight and auto-zoom are independent layers in Limelight. You can have the spotlight highlighting a region while auto-zoom zooms into specific click events within that region — the effects compose naturally.
- Is region spotlight useful for data privacy during recordings?
- Region spotlight is primarily an attention-direction tool, not a redaction tool. The dimmed area is visible, just darker. If you need to hide sensitive data, stop the recording, cover or navigate away from the sensitive content, and resume.
