Yes.

Look at the hotkeynet reference guide under ClickMouse for more information.

You could get some code like this:


Code:
<Hotkey LButton, RButton>
   <SendLabel wow1, wow2, wow3, wow4, wow5>
   <ClickMouse %TriggerMainKey%>
This will send left mouseclick or right mouse click resp to all 5 wow windows (again..just an example) without changing your current window.
