‘find-file-read-args’, so that ‘find-file’ (‘C-x C-f’) and related commands let you use ‘M-n’ in Dired to retrieve the file name under the cursor.

(DiredPlus also provides this behavior.)‘insert-directory’, so that Dired’s second header line lists the number of files in the directory, like this: files 691 space used 49439 available 56233408
