ありがとう、enyafriend!

can someone help me w/ the following? (how would ya say that in japanese?)
anyways, i've been using japan yahoo! dictionary, and i'm confused as to what the symbols mean, so i looked them up in the key (which confuses me too).

8 非常用漢字は漢字の左肩に×をつけて示した。
さんご【×珊×瑚】
i kinda get that it means "if a kanji has an x in the upper-left corner, it's not used".

9 常用漢字外の読みのものには、漢字の左肩に▲をつけて 示した。
さすが【▲流▲石】
i think this means that "if a kanji is not jouyou kanji, there is a triangle in the upper-left corner."

正解ですか。
