In the Search&Replace dialog, when marking the option "Search for Styles", it
should be possible to search for _all_ kinds of applied styles (dito for
replacement).

As far as I can see, currently only _paragraph_ styles can be searched (and
replaced). I sometimes want to look for all _emphasised_ or all _teletyped_
words in my text. Currently, I have to workaround this by
   1 study the actual formating attributes of the style in 
     interest by querying this style in the stylist (F11)
   1 adjust the "Format" in the Search&Replace dialog

For conservative enhancement, paragraph styles should become the default style.
But the "Search for Styles" entry should be accompanied by a "..." button, where
one can choose, which kind of styles should be used (paragraph, character,
frame, page, list).
