Most often, an Info cross reference looks like this:

*Note node-name::.

or like this

*Note cross-reference-name: node-name.

In TeX, a cross reference looks like this:

See Section section-number [node-name], page page.

or like this

See Section section-number [title-or-topic], page page.

The @xref command does not generate a period or comma to end the cross reference in either the Info file or the printed output. You must write that period or comma yourself; otherwise, Info will not recognize the end of the reference. (The @pxref command works differently. See section @pxref.)

Please note: A period or comma must follow the closing brace of an @xref. It is required to terminate the cross reference. This period or comma will appear in the output, both in the Info file and in the printed manual.

@xref must refer to an Info node by name. Use @node to define the node (see section How to Write an @node Line).

@xref is followed by several arguments inside braces, separated by commas. Whitespace before and after these commas is ignored.

A cross reference requires only the name of a node; but it may contain up to four additional arguments. Each of these variations produces a cross reference that looks somewhat different.

Please note: Commas separate arguments in a cross reference; avoid including them in the title or other part lest the formatters mistake them for separators.
