nice good you got it working!

one little cosmetic change in your script I would change is using <Sendlabel> instead of the five different <SendWinMF> like this:

<UseKeyAsModifier 7>
<Hotkey 7 LButton, MButton, RButton>
<SendLabel w1,w2,w3,w4,w5>
<ClickMouse %TriggerMainKey%>

..but this is purely cosmetic...
