Please add citations to all information you contribute. I know there are a lot on that list that aren't cited, but that needs to be corrected.

Consider also if some may be redundant. Is the "line" arrow essentially the same as the "rope" arrow with different phrasing? If there is a distinct difference a brief explanation would be helpful. A description of the "telescoping" arrow would be appreciated, too.

Thanks.
