One of the challenges, in creating a tutorial video via screen video capture, is that it becomes a challenge to make obvious which mouse action was used to produce a certain action on the screen.
The creator of this video has a little mouse icon in the bottom left of the screen (see image below) that makes clear whether he's using the left, the middle, or the right mouse click button action.
How does one add such a mouse icon (or alternatively, which software allows this) to a screen video capture? (I've asked the original creator on multiple fora, but haven't heard back for months).
