The code in Outlook looks more like this.
Untested.
Code:
Option Explicit
Public Sub PasteUnformatted()
Dim oDoc As Object
Dim itm As Object
Dim objSel As Word.Selection
On error resume next
Set itm = Application.ActiveInspector.CurrentItem
on error goto 0
if itm is nothing then
msgbox "Something wrong with current item"
exit sub
end if
If itm.GetInspector.EditorType = olEditorWord Then
Set oDoc = itm.GetInspector.WordEditor
Set objSel = objDoc.Windows(1).Selection
objSel.PasteSpecial Link:=False, DataType:=wdPasteText
End If
End Sub
No shortcuts except Alt+number shortcuts.
