Hi Brian, thank you for taking the time to help. I am looking for hardware something like this http://www.amazon.co.uk/Kensington-Si600-W...r/dp/B000FPGP4U but wonder how well they work with a finished presentation. I set my shows so that a left click moves forward one slide and a right click moves one slide backward, but as PTE gives so may options for the response to mouse clicks, I wondered if there are any presentation tools that could be made to work with a program that allows such great creator flexibility.
