What is a Mouse Trail?

A mouse trail is a visual effect that follows the motion of the pointer, leaving a temporary streak or a chain of fading copies behind it as it moves. The trail fades quickly once the cursor stops, so it represents movement rather than position. Older operating systems offered mouse trails as an accessibility aid, and some presentation tools use a stylized version to make fast cursor movements easier to track.

A mouse trail is different from a cursor highlight or cursor spotlight, which mark the current pointer position rather than its path. It also differs from click highlighting, which fires only on button presses, and from a magnifier, which enlarges content under the pointer. A trail is specifically about showing where the pointer has just been.

In screen presenting and recording, a trail can help an audience follow rapid mouse movement, though many presenters prefer a steady highlight to avoid visual clutter. Limelight does not draw mouse trails; its cursor spotlight is a soft glow that stays centered on the current pointer position rather than streaking behind it. As a menu-bar overlay, Limelight keeps the live pointer easy to see on top of any macOS app without leaving a trailing effect.
