Thanks a lot, its works perfectly

Now i can broadcast the mouse clicks on all my windows and gathering with all my toons !

Its the script I used, if someone is interested :

<UseKeyAsModifier Tab>

<Hotkey Tab LButton>
<If MouseIsOverWindowRect WoW1 0 0 1920 1080>
<SendLabel w1, w2, w3, w4>
<Clickmouse LButton>
<RestoreMousePos>
<Else>
<SendFocusWin>
<Clickmouse LButton>
