Unfortunately that would not work in this case as its not me showing a presentation. The student is on his/her own laptop either in my computer lab or at home and needs to ring the bell sound when the next click happens. Like this:

Screen appears with an example of the page that's being worked on.
With the page, comes an instruction for the student to complete in the other word processor that they are working with but they need to know when to switch to the other live program to do the operation so upon the next click of the mouse the bell sounds giving them that signal.

I'm not ringing the bell, they are.

Any ideas on how to get the bell to ring when the student clicks the mouse on their own computer?

Thanks
