Bing now has a Visual Search for PowerShell cmdelts!

On the left there are Refiners used to narrow down your selection by Category, Verb, Noun, and other groupings. 

After clicking on a cmdlet, you get a details “help” pane on the right with example usage and the top web results (typically TechNet or MSDN reference links).

Check it out:
