Yes, this is what the default in the engine does:

Code:

action _toggle_screen
{
    if (key_alt == 0)
    {
        return;
    }
    temp = video_screen + 1;
    if (temp > 2)
    {
        temp = 1;
    }
    video_switch(0,0,temp);
    if (result == 0)
    {
        beep;
    }
}

on_enter _toggle_screen;


Never argue with an idiot. They drag you down to their level then beat you with experience
