.. describe:: keyword
- The name of a keyword in Python.
+ The name of a Python keyword. Using this role will generate a link to the
+ documentation of the keyword. ``True``, ``False`` and ``None`` do not use
+ this role, but simple code markup (````True````), given that they're
+ fundamental to the language and should be known to any programmer.
