Summary: Find information, beyond the basics, for the Windows PowerShell variable ErrorActionPreference.

 How can I use Windows PowerShell to see information, beyond only the value, for the variable ErrorActionPreference?

 Use the Get-Variable cmdlet and pipe the results to the Format-List cmdlet:

Get-Variable ErrorActionPreference | Format-List *

Note  When you use the *variable cmdlets, you do not specify the initial dollar sign.
So it is represented as ErrorActionPreference not $ErrorActionPreference.
