In this article I reviewed the Logitech wireless presenter. It is in my opinion the best remote control to use with Keynote. That particular Logitech remote has been replaced by the new Logitech R400 which doesn’t feel as robust, the main buttons are smaller, and it still has the 2 smaller buttons, one which completely exits out of your keynote presentation! The last thing you want is to press the wrong button and be taken out of your keynote back to the desktop.
The smaller two buttons can be easily disabled with a knife. This article describes how to disable the extra 2 buttons. It really is a simple procedure and doesn’t even require any soldering!
