Summary: Show the Windows PowerShell ISE command pane on the left side of the screen.

 How can I split the PowerShell ISE screen vertically so I can see the screen pane on the right and the
           command pane on the left?

 To show a vertical configuration, select Show Script Pane Right from the View menu. Or use <CTRL-2> 
           to show the script pane on the right, and use <CTRL-1>to go back to the horizontal configuration.
