You edit multiple pages

You can use the Search & Remove Text command to achieve something similar, but it will only work correctly if:

- The new text is more or less the same length as the old one (for example, if you replace "apple" with "orange", but not if you replace "apple" with "grapefruit"), as it will not "re-flow" the rest of the text automatically.

- The old text is not placed on top of an image or other kind of graphic.

- The properties (font, size, color, etc.) of the old text are the same for all instances of it, and known to you.

In Acrobat, no. If you have access to the original document, the application that created that document can probably do that. Otherwise, the next best option would be to export the contents into a Word document, do what you need to do, and re-PDF the file.
