If in Keyclone, you go Set Up >> General >> "pass-mouse-click hotkey".
The default is F7, but you can change it to whatever.

In my experience, you're better off ignoring this feature.
Just put Hurricane on whatever keybind, and press the keybind.
Then move your mouse to each of the windows, to move the targeting circle.
Position as desired and click.
Then move to the next frame.
This procedure is far faster then the limited mouse-broadcast included in KC.
