@inforef: Cross-references to Info-only Material ¶@inforef is used for making cross-references to Info

@xref, @ref or @pxref with the Info
file name as the fourth argument and no fifth argument.
The command takes either two or three arguments, in the following order:
The template is:
@inforef{node-name, cross-reference-name, info-file-name}
