I meant other commands like `dired-next-line', just for comparison.

But it's rather convenient to keep in memory that:

1) First mark files you want to process.  To augment mark behaviour
(e.g. mark all files in a subdir) specify prefix arg to the mark command
or use a corresponding specific command.

2) Perform search/replace.  To augment search/replace behavior (like
toggle word searching) you have to specify prefix argument to the
search/replace command.

Yes, my comment was just a note.
