Additionally, there's another Enter key symbol: ⌅ (a "projective"). It's very similar to ⌤ (an "up arrowhead between two horizontal bars"), but it was also used to symbolize a column break.

The projective was used more commonly on Macintosh keyboards to symbolize the Enter key, and the up arrowhead between two bars was more in software menus.
