dired Emacs directory editor

Rename files with WDired mode
The names in a dired directory listing can be renamed by editing the file names in the dired buffer and committing the changes.

@ a to run the macro and repeat the same change
24 @ a to run the macro on the next 24 lines including the current line, repeating the same change on multiple file names in the dired buffer.
Reset cursor position at end of macro
If using positional aspects for changes made by the macro ensure the cursor is moved back to the correct starting place just before ending the macro recording.
