@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}.)
sometimes 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 which are loaded into the
current Emacs session or are auto-loaded (@pxref{Autoload,,, elisp,
The Emacs Lisp Reference Manual}). If @kbd{M-.} fails to find some
identifiers, you can try forcing @code{xref} to use the @code{etags}
backend (@pxref{Xref}). To this end, turn on the Xref Etags minor
mode with @w{@kbd{M-x xref-etags-mode}}, then invoke @kbd{M-.} again.
(For this to work, be sure to run @command{etags} to create the tags
table in the directory tree of the source files, see @ref{Create Tags
Table}.)
