Are you asking for an automatic way to do that? You could use If-Else just like you did with <Hotkey 2>. For example, to broadcast every key on the keyboard (except the ones you're using for special purposes) but only when the WoWs are active:

Code:
<Hotkey AllMainKeys except F1, 1, 2>
   <If ActiveWinIs wow1>
      <SendLabel w1, w2>
         <Key %Trigger%>
   <Else If ActiveWinIs wow2>
      <SendLabel w1, w2>
         <Key %Trigger%>
   <Else>
         <SendFocusWin>
         <Key %Trigger%>
That takes care of 190 keys.
