 @findex xref-etags-mode
   Some major modes install @code{xref} support facilities that might
-fail to find certain identifiers.  For example, in Emacs Lisp mode
-(@pxref{Lisp Eval}) @kbd{M-.} will by default find only functions and
-variables from Lisp packages that are loaded into the current Emacs
-session.  To find more identifiers, turn on the Xref Etags minor mode
-with @w{@kbd{M-x xref-etags-mode}}.  This command forces @code{xref}
-to use the @code{etags} backend (@pxref{Xref}).  (For this to work,
-you should first run @command{etags} to create the tags table, see
-@ref{Create Tags Table}.)
