@xref
with Two Arguments
With two arguments, the second is used as the name of the Info cross reference, while the first is still the name of the node to which the cross reference points.
The template is like this:
@xref{node-name, cross-reference-name}.
For example,
@xref{Electrical Effects, Lightning}.
produces:
*Note Lightning: Electrical Effects.
and
See Section 5.2 [Electrical Effects], page 57.
(Note that in the preceding example the closing brace is followed by a period; and that the node name is printed, not the cross reference name.)
You can write a clause after the cross reference, like this:
@xref{Electrical Effects, Lightning}, for more info.
which produces
*Note Lightning: Electrical Effects, for more info.
and
See Section 5.2 [Electrical Effects], page 57, for more info.
(Note that in the preceding example the closing brace is followed by a comma, and then by the clause, which is followed by a period.)
