Sorry, Pete: I misunderstood you.

Here is code I use to insert text in a Word formfield. FWIW, I much prefer form fields to mergefields. This is from a button on a Word form where users fill in the documents fields. I'm just getting started with VBA myself, but I think there is a collection called MergeFields. But, if you just type in "activedocuments." in a VBA code window, you should see a list of all valid properties and methods for it.

Private Sub CommandButton1_Click()
    With UserForm1
        ActiveDocument.FormFields(.listFormFields.List(.listFormFields.ListIndex, 1)).Result = .txtField.Value
        ActiveDocument.FormFields(.listFormFields.List(.listFormFields.ListIndex, 1)).TextInput.Default = _
            ActiveDocument.FormFields(.listFormFields.List(.listFormFields.ListIndex, 1)).Result
        UserForm1.listFormFields.SetFocus
    End With
End Sub
