54 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. Clicking Mouse-1
quickly on the link also follows it. (Hold Mouse-1 for longer
if you want to set point instead.)
Info mode, Help mode and the Dired-like modes are examples of modes
that have links in the buffer. The Tags facility links between uses
and definitions in source files, see Tags. Imenu provides
navigation amongst items indexed in the current buffer, see
Imenu. Info-lookup provides mode-specific lookup of definitions
in Info indexes, see Documentation. Speedbar maintains a frame
in which links to files, and locations in files are displayed, see
Speedbar.
Other non-mode-specific facilities described in this section enable
following links from the current buffer in a context-sensitive
fashion.
