Customizing PowerShell ISE with Yank Line CustomMenu Item

I was excited to hear that the PowerShell ISE editor was based on the new WPF editor that will ship in Visual Studio 2010.  However I was disappointed when I couldn’t find one of my favorite shortcuts in the script editor: Ctrl+L a.k.a. yank line.  Fortunately the object model for the editor is capable enough to support this capability.  Here’s a pretty simple custom menu entry with an assigned keyboard shortcut (Ctrl+L) to perform a yank line in the editor:

   1: [void]$psISE.CustomMenu.Submenus.Add(

   2:     'Yank Line', 

   3:     {

   4:       $editor = $psise.CurrentOpenedFile.Editor

   5:       $line = $editor.CaretLine

   6:       $lineLen = $editor.GetLineLength($line)

   7:       if ($line -lt $editor.LineCount) 

   8:       {

   9:         $editor.Select($line, 1, $line + 1, 1)

  10:       }

  11:       else

  12:       {

  13:         $editor.Select($line, 1, $line, $lineLen + 1)

  14:       }

  15:       [System.Windows.Clipboard]::SetText($editor.SelectedText)

  16:       $editor.InsertText('')

  17:     }, 

  18:     'Ctrl+L'

  19: )

I find this handy for copying an entire line.  I yank the line that I want to copy to the clipboard.  Once it is yanked, I can paste it back as many times as I need.
