What is the diffrence there? ..() has always worked for me, but I am unsure what good .=..() does. I looked up ., and I looked up .., and .=..() still made no since to me. So if anyone would mind explaining it to me, that would be peachy kean.

"." is the default return value.
"..()" calls the parent procedure.

Setting "." to "..()" (.=..()) will make a proc return it's parents return value. It's essentially the same as return ..(), but it doesn't force the proc to return right then, which can be handy. =)

It's considerably useful in Enter().

Ok, I guess that makes sense. I dont see the practicle use for it, although I am sure there is some.
