Hot keys are useful. When used properly, it really makes you work much efficient. But when too many apps configured with its own hot keys, it may get conflict each other. It would be nice having a little tool that can help find out what keys are registered and what are available.

It runs on any version of Windows, from XP and up to Windows 8 with the support for both 32-bit and 64-bit editions.
