Newbie Docs question: what does the "#" symbol mean in the docs, like "ReactiveDict#all()"?

Sometimes in the docs, they use a “#” instead of a period. Example:


Other times, it uses the period:


What is the significance of the “#” sign?

My guess:
Is the “#” mean that it’s a method called on an instance?


Consider, for example, documentation - Referring to javascript instance methods with a pound/hash sign - Stack Overflow

I think it’s just an instance method and I won’t read too much into it.

I think the idea with the # sign was to denote the existence of a certain function in a given scope, whereas the dot is best used to demonstrate an invocation of a function. But it’s used in the Meteor docs somewhat ambiguously.
