Ctrl+x-d(dired) or kbd[Ctrl+x] - Ctrl+f(find file)

Mark files for deletion

d

Remove the deletion flag

u

Execute the deletion

x

Flag all auto-save files (files whose names start and end with ‘#’) for deletion.

#

Flag all backup files (files whose names end with ‘~’) for deletion.

~

Visit(open) the file described on the current line.

f or Ret or e

Like f, but uses another window to display the file’s buffer. The Dired buffer remains visible in the first window. This is like using Ctrl+x 4 Ctrl+f to visit the file.

o

Visit the file described on the current line, and display the buffer in another window, but do not select that window.

Ctrl+o

View the file described on the current line, with View mode. View mode provides convenient commands to navigate the buffer but forbids changing it.

v

Visit the parent directory of the current directory. This is equivalent to moving to the line for .. and typing f there.

^

Dired Marks

Instead of flagging a file with ‘D’, you can mark the file with some other character (usually ‘’). Most Dired commands to operate on files use the files marked with ‘’. The only command that operates on flagged files is x, which deletes them.

Mark the current file with ‘*’(dired-mark). If the region is active, mark all files in the region instead; otherwise, if a numeric argument n is supplied, mark the next n files instead, starting with the current file(if n is negative, mark the previous -n files).

m or * m

Mark all executable files with ‘*’(dired-mark-executables). With a numeric argument, unmark all those files.

* *
