If you are a programmer you probably heard about the GetSystemMetrics Function, which "Retrieves the specified system metric or system configuration setting." See http://msdn2.microsoft.com/en-us/library/ms724385.aspx
Me, I'm sometimes curious. For example I want to know The minimum width of a window, in pixels. This is easy now, because I gave me (and you!) an interface to GetSystemMetrics via scripting!
Try this:
::gsm 28
And you know The minimum width of a window, in pixels on your computer.

Other magical numbers are found under the link above...
