Query: Keyspan Presentation Remotes

This isn't the flashiest remote on the planet, but we've found it easy to use on both PC and Mac machines. Having the pointer feature was something everybody wanted, along with being able to walk around and still advance the frames. We give new remotes to new faculty and I've had several requests for replacements after we've used the old ones to death, so everybody seems happy.
