A family of Microsoft word processing software products for creating web, email, and print documents.
Sorry about the AutoNew macro; it looks like Word 2013 doesn't trigger the New command when it makes the blank document at startup.
The problem with AutoExec is that at the time that macro runs, there is no document and therefore no ActiveWindow or View to set the type in. That requires a workaround, similar to the one in http://www.word.mvps.org/FAQs/Userforms/AutoExecUsertFm.htm. I've verified that this works:
Sub AutoExec()
Application.OnTime _
When:=Now + TimeValue("00:00:01"), _
Name:="WebView"
End Sub
Sub WebView()
ActiveWindow.View.Type = wdWebView
End Sub
