PC Magazine WinPointer

With WinPointer is easy to highlight certain key areas of a screen to make a point, or for emphasis.

You can use WinPointer to annotate screens to send to others, and even to help with documentation and canned presentations.
WinPointer remains easy to use. Simply start it up, and the program nestles out of sight in the system tray, ready for either a right-click activation or a hot key to put it to work.
