I was working on an omnibus epub: one made by merging several books, and at the first stage this had several CSS files, one for each individual book, linked from the HTML files for that book.

I wanted to make changes to all of them, but selecting them all and choosing "replace all" for "selected files" gave "no replacements made"; similarly "find" gave "no matches found". I had to choose one CSS file and do "current file".

Not a common situation I admit, but would be logical and convenient to have "selected" work the same for CSS as it does for HTML.
