reftex: Options - Viewing Cross-References

 
 18.7 Viewing Cross-References
 =============================
 
  -- User Option: reftex-view-crossref-extra
      Macros which can be used for the display of cross references.  This
      is used when ‘reftex-view-crossref’ is called with point in an
      argument of a macro.  Note that crossref viewing for citations,
      references (both ways) and index entries is hard-coded.  This
      variable is only to configure additional structures for which
      crossreference viewing can be useful.  Each entry has the structure
           (MACRO-RE SEARCH-RE HIGHLIGHT).
      MACRO-RE is matched against the macro.  SEARCH-RE is the regexp
      used to search for cross references.  ‘%s’ in this regexp is
      replaced with the macro argument at point.  HIGHLIGHT is an integer
      indicating which subgroup of the match should be highlighted.
 
  -- User Option: reftex-auto-view-crossref
      Non-‘nil’ means, initially turn automatic viewing of crossref info
      on.  Automatic viewing of crossref info normally uses the echo
      area.  Whenever point is idle for more than ‘reftex-idle-time’
      seconds on the argument of a ‘\ref’ or ‘\cite’ macro, and no other
      message is being displayed, the echo area will display information
      about that cross reference.  You can also set the variable to the
      symbol ‘window’.  In this case a small temporary window is used for
      the display.  This feature can be turned on and off from the menu
      (Ref->Options).
 
  -- User Option: reftex-idle-time
      Time (secs) Emacs has to be idle before automatic crossref display
      or toc recentering is done.
 
  -- User Option: reftex-cite-view-format
      Citation format used to display citation info in the message area.
      See the variable ‘reftex-cite-format’ for possible percent escapes.
 
  -- User Option: reftex-revisit-to-echo
      Non-‘nil’ means, automatic citation display will revisit files if
      necessary.  When ‘nil’, citation display in echo area will only be
      active for cached echo strings (see ‘reftex-cache-cite-echo’), or
      for BibTeX database files which are already visited by a live
      associated buffers.
 
  -- User Option: reftex-cache-cite-echo
      Non-‘nil’ means, the information displayed in the echo area for
      cite macros (see variable ‘reftex-auto-view-crossref’) is cached
      and saved along with the parsing information.  The cache survives
      document scans.  In order to clear it, use ‘M-x reftex-reset-mode’.
