Shift-Cmd-P will activate/deactivate the Preview pane. It's also on the menu under View > Show Preview.
It creates another column to the right of your directory and will show a preview of text, image and video files. You can also edit text files right in the Preview pane.
I have ForkLift configured to show two directory listings, one above the other (instead of side-by-side)... and the Preview pane is displayed to the right of that.
Manage your files quickly across local drives and remote servers with ease. ForkLift is a robust FTP/SFTP/WebDAV/Amazon S3/Backblaze B2/Google Drive/Rackspace Cloud Files client and a powerful and versatile file manager.
