Re: rcirc manual

[Richard M. Stallman]

      For example, you
    could use either @address@hidden or @kbd{M-x} (since `x' ``describes a
    key by name''), but the Texinfo manual doesn't touch this dilemma.

For key names that are spelled out, such as TAB, always use @key.
That includes @address@hidden  You will see that in the Emacs
manual.

There is an exception for index entries.
