Yes, but I wouldn't recommend doing it wholesale

. I would create a
template with the following macros and use it for documents that you want use
this feature for:
Sub AutoNew()
'Assigns the Macro1 Macro to the ENTER Key
CustomizationContext = ActiveDocument.AttachedTemplate
KeyBindings.Add KeyCode:=BuildKeyCode(wdKeyReturn), _
KeyCategory:=wdKeyCategoryMacro, Command:="Macro1"
End Sub
Sub AutoOpen()
'Assigns the Macro1 Macro to the ENTER Key
CustomizationContext = ActiveDocument.AttachedTemplate
KeyBindings.Add KeyCode:=BuildKeyCode(wdKeyReturn), _
KeyCategory:=wdKeyCategoryMacro, Command:="Macro1"
End Sub
Sub AutoClose()
CustomizationContext = ActiveDocument.AttachedTemplate
FindKey(KeyCode:=BuildKeyCode(wdKeyReturn)).Disable
'Disables prompt to save template changes
Templates(1).Save
End Sub
Sub Macro1()
