Technically, the original Caesar was supposed to be a -3, and there was only one, so "Caesar cipher" means what you mean; no need for the +3.

Also, if you'll note, it's actually shifted -3...(maybe there's some naming convention I'm not aware of?)

If the amount you shift by is anything anything other than -3, the typical way to denote it is ROT_whatevernumber_. You used ROT23.

(ROT stands for rotate by).
