PowerShell v2 v3 Quick Way to List Automatic Variable Names

Nothing more than a tidbit to remind myself:

(get-help about_Automatic_Variables) -split "`n" | where {$_ -match ^    $}

This should spit out something like this in v3:

$$

$?

$^

$_

$Args

$ConsoleFileName

$Error

$EventArgs

$EventSubscriber

$ExecutionContext

$False

$ForEach

$Home

$Host

$Input

$LastExitCode

$Matches

$MyInvocation

$NestedPromptLevel

$NULL

$PID

$Profile

$PSBoundParameters

$PsCmdlet

$PSCommandPath

$PsCulture

$PSDebugContext

$PsHome

$PSScriptRoot

$PSSenderInfo

$PsUICulture

$PsVersionTable

$Pwd

$ReportErrorShowExceptionClass

$ReportErrorShowInnerException

$ReportErrorShowSource

$ReportErrorShowStackTrace

$Sender

$ShellID

$StackTrace

$This

$True
