There are many ways to add a cross reference: @xref (starts a
sentence), @ref (at the end of a sentence), @pxref (within
parentheses) etc.

And the arguments are not immutable.  Apart from the node name, it can
also contain the cross reference name (although usually omitted),
section name (used in printed manual), Info file name (if it is
different from the current file, for example, an @pxref from
doc/lispref/ to doc/emacs/) and printed manual name.

Do you want a general command or a specific command[1]?
