Salling Clicker lets a phone be used to control a computer: The software started as a Mac-only product that worked with Bluetooth to handle presentation advances and a few other limited options. The product has gradually become richer and richer, and long ago added Windows support. The latest release extends Wi-Fi support for smartphones that include Wi-Fi, and uses auto-discovery with Symbian and Windows Mobile 3.5 to allow computers to find all Salling Clicker-enabled phones.
