Of course, you have the option of changing the appearance of your cursor, highlights and click effects. If you don't want to highlight with a circle, you have a choice of 18 different shapes. If you don't want rings indicating a click, use a circle. And the decision of the color of any of these if left to your discretion. Cursor Sounds makes your video play a clicking noise when you perform an action, and you have the option of importing a cursor sound from another file.
Viewers can then hear the action while seeing it happen.
And, if you need the cursor and the cursor's actions to be invisible and silent, you can simply choose Hide Cursor. Try adding Cursor Effects to your next Camtasia recording. Or you can select effects using the Cursor Toolbar. The cursor is hidden during video capture. This selection toggles with Show Cursor.
