There are several Dired commands for visiting or examining the files listed in the Dired buffer. All of them apply to the current line’s file; if that file is really a directory, these commands invoke Dired on that subdirectory (making a separate Dired buffer).
Visit the file described on the current line, like typing C-x C-f
and supplying that file name (
dired-find-file). See Visiting Files.
Equivalent to f.
Like f, but uses another window to display the file’s buffer
dired-find-file-other-window). The Dired buffer remains visible
in the first window. This is like using C-x 4 C-f to visit the
file. See Multiple Windows.
Visit the file described on the current line, and display the buffer in
another window, but do not select that window (
Visit the file whose name you clicked on
dired-mouse-find-file-other-window). This uses another window
to display the file, like the o command.
View the file described on the current line, with View mode
dired-view-file). View mode provides convenient commands to
navigate the buffer but forbids changing it; See View Mode.
Visit the parent directory of the current directory
dired-up-directory). This is equivalent to moving to the line
for .. and typing f there.
When visiting a new sub-directory in Dired, Emacs will (by default)
open a new buffer to display this new directory, and leave the old
Dired buffer as is. If this user option is non-
nil, the old
Dired buffer will be killed after selecting the new directory. This
means that if you’re traversing a directory structure in Dired, you
won’t end up with more than a single Dired buffer.
