Dope Sheet

Dope sheets are made by animators to indicate where the sound is going to be in frames to help de-construct a soundtrack; this includes dialogue, music and foley tracks. Commonly, there are columns called "Action" and "Dial" and 24 or 25 rows for each second. There are usually more rows, depending on how long the soundtrack is. 

The Action column is obvious: its used for planning out where the action is going to happen and also how long it is going to take. 

The Dial column is short for dialogue and is used for planning out the words been spoken in that sequence. For foley too, the animator can write down words to represent that sound. For example, if they wanted a "Crash!" sound, they can write out "CRRAAASSSSHHHH" in the dialogue column down the row to indicate the timing of that in frames.
