Re: ME3 LE: No button on my keyboard skips dialogue

It works with the spacebar in ME1 and ME2 LE, but not with ME3 for some mysterious reason.  

It was my problem six months ago; I uninstalled it, reinstalled it, and had to verify the files because of a bug in ME2, but it still doesn't allow me to skip with spacebar or any other button.  

The problem persists; I tried to find out how to configure hidden hot keys in the game, but I don't know how to do it with ME3...
