title: How to tell if Hotkey combination already exists
body: <p>I am using Registerhotkey to allow my users to define custom key combinations to perform different actions. The problem I seem to be having is that there is currently no way to check if the key already exists.</p>
  
  <p>For example: One of my testers tried to define "Windows Key + D" not knowing that is the key combination to minimize all windows. So I was curious if there was any way to tell if given a key combination that I could check if that key combination already exists by windows or any other application.</p>
