Had to do a minor change. For some reason when adding LavaB to "F" priority casting list my slave bugged out a bit and started casting Lightning Bolts as a starter, LavaB was supposed to be the starter. After a couple of minutes I figured it might be that I ingame had F keybound to Lightning Bolt. So i canged my apply template for F to only work as Output for the master (or focus win) and then translate to an unbound input key for the slave. In this case "3".

Code:
<Hotkey RAlt F10>
    <SendLabel w1>
        <Key 2>
        <Key E>
        <Key Q>
        <Key F>

    <SendLabel w2>
        <Key 2>
        <Key E>
        <Key Q>
        <Key F>

<Hotkey RAlt F9>
    <SendLabel w1>
        <Key 1>

    <SendLabel w2>
        <Key 1>
