how select multiple scrivener text doc and change?

I want to change multiple texts, for example remove color in these. Is it possible?

The Scrivenings view, you may have noticed, is not yet integrated. If you press Ctrl-A for instance to select all text, it only selects within the boundary of the section you are editing. Thus, cross-file edits to formatting cannot be made at this time.

One thing you may consider is just not worrying about it and stripping out colours when you compile. There is an option for it in the Transformations compile option pane, “Remove text color”.

ok, no problem, whan I imported my doc manuscript, I didnt know this, but no problem, is small detail
