The PowerShell team blogged about a new visual search capability for Powershell help care of Bing

Couple of points
– make sure that you are looking at the US version of Bing – it doesn’t show in others (at least it doesn’t in the UK version)
– click on the country name at top right on the bing welcome page and select United States – English
– select Visual Search
– select Reference
– scroll down for PowerShell – under the Scripting heading
Only the core PowerShell cmdlets are available – hopefully other teams will follow suit.
