If you work with WIX installers you will want and easy way to create and paste guids into your code.
Visual Studio 2012 has a create GUID tool but it is too slow. I wanted a simple keystroke.
After looking at addins to VS2012 I decide it was too much trouble.
The 3 minute solution:
Install AutoHotkey, and let it create a sample script for you the first time it runs.
Replace that script with the one found here.
And now Window-Shift-G does exactly what I wanted.
Thanks to both AutoHotKey and Ian Prest
