How do I prevent Construct games from quick find shortcut ?

Hello !

I made a game on Newgrounds :

https://www.newgrounds.com/portal/view/709393

My problem is that when you use the key "4", on firefox it open the shortcut "quick find", and leave the focus on the game.

Is there a way to keep focus on the game ?

In construct, I tried the browser action "Focus" but it doesn' work...

Any idea ?

Thanks.

OK I found the answer by myself.
