The documented commands from the directory window are Ctrl-S or Ctrl-G, which will show all tagged files in all directories of either the current disk or all logged disks. Or you can key Ctrl-B, which will show all tagged files in the branch defined by the highlight position. But what if you want to show only the tagged files in the current directory? The undocumented command for this is Ctrl-F4 from the file window.
