(reftex)Options (Viewing Cross-References)
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 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 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 of from the menu (Ref->Options). - User Option: reftex-idle-time Time (secs) Emacs has to be idle before automatic crossref display 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'.
