@kindex = @r{(Dired)}
Compare the current file (the file at point) with another file (the
file at the mark) using the @code{diff} program (@code{dired-diff}).

file at point is the second argument. This refers to the ordinary

The @kbd{=} (@code{dired-diff}) command compares the current file
(the file at point) with another file (read using the minibuffer)
using the @command{diff} program. The file specified with the
minibuffer is the first argument of @command{diff}, and file at point
is the second argument. The output of the @command{diff} program is
shown in a buffer using Diff mode (@pxref{Comparing Files}).
@findex dired-backup-diff

@item M-=
Compare the current file with its latest backup file
(@code{dired-backup-diff}). If the current file is itself a backup,
compare it with the file it is a backup of; this way, you can compare
a file with any one of its backups.
The backup file is the first file given to @code{diff}.

If the region is active, the default for the file read using the
minibuffer is the file at the mark (i.e.@: the ordinary Emacs mark,
