Ray grabber?

[CDreiser]

I have seen a post in the past about a ray grabber, e.g. the ability to grab an object from a distance via a ray tool such as laser pointer or examiner rather than by the hand grabber. For my current project, this type of tool is necessary. If one exists, how would I go about using it? If one does not exist, I can make my own code to implement this without many issues, but I need a method to retrieve the object either highlighted by the examiner or pointed to by the laser pointer. Does such a method exist?
