References to backslash in Texinfo manual



Hi, I got this message:

Section 5.2.1 is about strings and among other things
it describes what effect backslash has in a string.
Is there a way to make a reference to that section so
that someone looking for "\" or "backslash" can find it?
I tinkered with using @anchor but I couldn't get it to work.

I suppose in addition there should be a reference to the
section about symbols, 6.3 "Identifiers". (Hmm, I suppose
that should be renamed to "Symbols".)

I hope someone can handle this --

best,
