The default styles in Writer for links (“Internet Link”, “Visited Internet Link”) do not show up in the styles list like other styes, and there doesn’t appear to be any way to mass modify those styles for formatting of all occurrences in the same document. The only way I’ve found to do this so far is the very tedious process of selecting each text string with a defined link and manually editing the character attributes to change the default hyperlink styles for visited and unvisted link to a different user-defined style. Am I overlooking something, or is it really this difficult? The default styles for links make the text in many documents almost unreadable, and in some contexts one doesn’t want to visually distinguish visited/unvisited links.
This seems to be a generic problem when you need to change many disconnected parts of a document from a default style to some user-defined style, which is an issue one frequently encounters with when combining text from a variety of sources. What would really be nice in cases like this would be a “Style Find & Replace” that would replace all usage of one style, including default styles, with another style in contexts where the styles are compatible.
