GNU Emacs Manual
AC.28 Hyperlinking and Navigation Features
Various modes documented elsewhere have hypertext features so that
you can follow links, usually by clicking Mouse-2 on the link or
typing RET while point is on the link. Info mode, Help mode and
the Dired-like modes are examples. The Tags facility links between
uses and definitions in source files, see W.2 Tags Tables. Imenu provides
navigation amongst items indexed in the current buffer, see
U.2.3 Imenu. Info-lookup provides mode-specific lookup of definitions
in Info indexes, see U.6 Documentation Lookup. Speedbar maintains a frame
in which links to files, and locations in files are displayed, see
P.9 Making and Using a Speedbar Frame.
Other non-mode-specific facilities described in this section enable
following links from the current buffer in a context-sensitive
fashion.
