Describes how to retrieve and run commands in the command history.

	When you enter a command at the command prompt, Windows PowerShell
	saves the command in the command history. You can use the commands
	in the history as a record of your work. And, you can recall and run the 
	commands from the command history.

  History Cmdlets
	Windows PowerShell has a set of cmdlets that manage the command history.

		Cmdlet (Alias)	 Description
		-------------------  ------------------------------------------
		Get-History (h)	Gets the command history.

		Invoke-History (r)   Runs a command in the command history.

		Add-History		Adds a command to the command history.

		Clear-History (clh)  Deletes commands from the command history.

  Keyboard Shortcuts for Managing History
	In the Windows PowerShell console, you can use the following shortcuts
	to manage the command history.

	For other host applications, see the product documentation.

		Use this key	To perform this action
		-------------	 ----------------------------------------------
		UP ARROW		Displays the previous command.
		DOWN ARROW		Displays the next command.
		F7				Displays the command history. 
							To hide the history, press ESC.
		F8				Finds a command. Type one or more characters,
							and then press F8. For the next instance, 
							press F8 again.

		F9				Find a command by history ID. Type the history
							ID, and then press F9. To find the ID, press F7.

	The $MaximumHistoryCount preference variable determines the maximum
	number of commands that Windows PowerShell saves in the command history.
	The default value is 64, meaning that Windows PowerShell saves the 64
	most recent commands, but you can change the value of the variable.

	For example, the following command raises the $MaximumHistoryCount to
	100 commands:

		$MaximumHistoryCount = 100

	To apply the setting, restart Windows PowerShell. 

	To save the new variable value for all your Windows PowerShell
	sessions, add the assignment statement to a Windows PowerShell profile.
	For more information, see about_Profiles.

  Order of Commands in the History
	Commands are added to the history when the command finishes executing,
	not when the command is entered. If commands take some time to be 
	completed, or if the commands are executing in a nested prompt, the
	commands might appear to be out of order in the history. (Commands
	that are executing in a nested prompt are completed only when you exit 
	the prompt level.)
