For example, +the code using @code{gmhist} history functions was replaced with code using +the mini-buffer history now built into GNU Emacs 19. Finally, a few other +features have been added and a few more functions have been bound to keys. + +Please note that @file{dired-x.el} and this texinfo file @file{dired-x.texi} +are bundled with GNU Emacs versions 19.23 and later. + +@ifinfo +@menu +* Features:: +* Technical Details:: +@end menu +@end ifinfo + +@node Features, Technical Details, Introduction, Introduction +@comment node-name, next, previous, up +@section Features +@cindex Features + +Some features provided by Dired Extra + +@enumerate +@item +Omitting of uninteresting files from dired listing. +@itemize @bullet +@xref{Omitting Files in Dired} +@end itemize +@item +Local variables for dired directories. +@itemize @bullet +@xref{Local Variables} +@end itemize +@item +Guessing shell commands in dired buffers. +@itemize @bullet +@xref{Shell Command Guessing} +@end itemize +@item +Running dired command in non-dired buffers. +@itemize @bullet +@xref{Virtual Dired} +@end itemize +@item +Finding a file mentioned in a buffer +@itemize @bullet +@xref{Find File At Point} +@end itemize +@item +Commands using file marking. +@itemize @bullet +@xref{Advanced Mark Commands} +@end itemize +@end enumerate + +@noindent +@file{dired-x.el} binds some functions to keys in Dired Mode (@xref{Key +Index}) and also binds @kbd{C-x C-j} and @kbd{C-x 4 C-j} @emph{globally} to +@code{dired-jump} (@xref{Miscellaneous Commands}).
