Highlight and AutoHighlight are helpful in drawing the viewer's attention to an exact area of the screen. Highlight allows you to select a window or portion of a window prior to recording. A colored highlight box will appear around this area in the video. AutoHighlight is similar, except that rather than staying in one place, the highlight follows the cursor as it moves across the screen while you're recording. You can adjust the color and width of the highlight.
Viewers sometimes find it difficult to find and follow the cursor in a screen capture video.
Use Zoom during recording to show more screen detail or cover more area. The plus and minus zoom options zoom the capture area in and out in increments, always maintaining the aspect ratio. The ZoomTo button will zoom directly to a certain size, or to a specific region, window or the full screen. The Zoom Undo button reverts back to the last zoom size and toggles between the last two zoom sizes. AutoZoom allows you to zoom between two windows, regions etc.
