Highlighter is compatible with Snow Leopard, Lion, Mountain Lion, Mavericks, and Yosemite.

Brief Description:

Highlighter was developed to assist with presentations or recorded tutorials. Help your audience focus on your actions by placing a red circle around your mouse as it moves about the display. When you click on the mouse, the red circle flashes blue and the area inside the circle is magnified by 30%.

Version 2.3.0 is compatible with Yosemite's default security.


The circle can be turned on and off with two shortcuts (Control-Shift to turn on, Option-Shift to turn off).


The small Control Panel may be dragged anywhere on the display. Click on the Control Panel to see the Highlighter menu bar where you can access the Preferences Window, the Help information, the AboutBox and Check for Updates. Close Highlighter by clicking on the Control Panel's red (close) button. The Control Panel may be minimized. You can set two preferences from the Preferences Window:

  • a. Turn off the circle after a mouse click.

  • b. Turn off the magnification.

  • You can also use shortcuts to turn the magnification on (Control-\) and off (Option-\). All four shortcuts may be used with the Control Panel minimized.

    Preferences and Control Panel window position are saved between sessions.
