Search and Replace
From Scribus Documentation Project
An advanced tool for searching and replacing or reformatting in text frames is Edit > Search/Replace. While the elements of the dialog are self-explanatory, you should be aware of the fact that it's an extremely versatile tool. That's because you can't just search for and replace identical content or properties, but use the tool to do this "asymmetrically". For instance, you can search for all instances of text formatted in a certain font and replace them with new text in another font and another font color. You can also specify if you want to perform a search for a whole word (i.e. a text string separated from other text by spaces) and if Scribus will use case sensitive or insensitive.
Please note that you have to find at least one matching instance in the text before you can start the replacement. In other words: you need to click on "Search" before you can use "Replace" or "Replace All".
You should also be aware of the fact that you can use this tool only for a single text frame or linked text frames, not for the whole document.
