[gram.key] says that some declarations introduce context-dependent keywords.

  1. How does a typedef declaration introduce context-dependent keywords, and what are they?
  2. Also, does a using-declaration not introduce keywords, but typedef does?
  3. Last but not least, are concepts missing from this section?

It does.

A typedef-name can also be introduced by an alias-declaration.

Concepts are covered by template, see [temp.pre]/1.

But these all introduce names (in the form of identifiers). I think it's a valid question how they are "context-dependent keywords".

If this subclause is supposed to be Informative, it should inform not confuse. What is the normative meaning of context-dependent keyword? Could we get an example of introducing one?
