Ditto

Ditto may mean several things:

ditto marks like ", 〃 or do. are used to mean "repeat the above info here". (Unicode: U+3003 (decimal: 12291).) It came from Italian ditto = "having been said", thus "what I just said", from Latin dictum.
likewise, "ditto" means "I agree" (I repeat your sentiment), or "use the same answer from the last question" (as in "what do I do with item one?", "throw it away"... "what about this other item?", "ditto")
