Use 'Screenshot' to take a screenshot of the entire screen but with a 10-second delay. During the delay, click the item of interest so the menu appears. The resulting screenshot will include the menu and pointer. I generally rename the .png to something meaningful; not just Screenshot...blah.png. I then open the .png in GIMP and crop to the area of interest.
