\title{Dired Reference Card}

\centerline{(based on Dired in GNU Emacs \versionemacs)}
\centerline{Commands marked with \dx{} require dired-x}

% trim this down to fit everything on one page
% \section{General}
% In dired, you can edit a list of the files in a directory (and optionally
% its subdirectories in the `ls -lR' format).

% Editing a directory means that you can visit, rename, copy, compress,
% load, byte-compile  files.  You can change files' attributes, run shell
% commands on files, or insert subdirectories into the edit buffer.  You can
% "flag" files for deletion or "mark" files for later commands, either one
% file at a time or by all files matching certain criteria (e.g., files that
% match a certain regexp).

% You move throughout the buffer using the usual cursor motion commands.
% Letters no longer insert themselves, but execute commands instead.  The
% digits (0-9) are prefix arguments.

% Most commands operate either on all marked files or on the current file if
% no files are marked.  Use a numeric prefix argument to operate on the next
% ARG files (or previous ARG if ARG $<$ 0).  Use the prefix argument `1' to
% operate on the current file only.  Prefix arguments override marks. Commands
% which run a sub-process on a group of files will display a list of files
% for which the sub-process failed.  Typing y will try to tell
% you what went wrong.

% When editing several directories in one buffer, each directory acts as a
% page, so C-x [ and C-x ] can be used to move between directories.
