I am trying the trial version of My Screen Recorder. I don't see any option for highlighting a point by drawing on the screen. Does your Pro version support this feature? If yes, how does it work?

Yes, My Screen Recorder Pro has a screen draw feature. You can select a pen or highlighter for drawing on the screen or highlighting your points. There is also an option to change the size and color for both. Follow this link to learn more about Screen Draw.
