Asok has a nice little utility called peep-dired that’s available from MELPA. It’s a Dired minor mode that displays the file at point in the dired buffer in another window. You don’t have to select the file or do anything special. As you move to another file in dired with 【Ctrl+n】 or 【Ctrl+p】, the new file is displayed.
You can ignore certain files and there are commands for cleaning things up. Take a look at the REAME to see the details. If you have a workflow that involves scrolling through a list of files, you may find this package a real win. My workflows don’t include this so I haven’t used the utility. If you have experience with it, leave a comment.
