something about auto_skip="1" and forced_skip="1"

[castled]

auto_skip="1" i name it A here for short, forced_skip="1" is F,
i can use them in activated, spell and trigged abillity , and take a same result that skip the chance of other spells to happen before its effect is effected.
e.g. instant cant happen when effecting with A and F. also, animation will be skiped.
and, there is something different between them, player can "pause" with A but not F.
but, it is bad to use them at sometime, like mana-produce with A but not F; and an abillity with "choose" uses A or F , spelled as an instant, during "playtime" of another with "choose", the game will easily run error. if the "another" uses script "regist", i can only restart computer to clean error…(is it unable to effect "choose" in the same moment?)
i only know so little, hope it could help some
