Thanks for posting this information on changing character fonts (http://support.biblioscape.com/node/963), very interesting. What would be even better to have is a way to access both Paragraph and Character styles already defined but the user in a Word/RTF document (or template). In any serious, extended document, styles are necessary and modifying text using fonts only is insufficient and when styles are already used - potentially messy. Access to styles would also allow for extended automated workflows beyond Word: e.g., Biblioscape - Word - InDesign (or FrameMaker).
Biblioscape does formatting
Biblioscape does formatting through RTF. Anything supported in RTF can be used in Biblioscape. If you want to include styles in Biblioscape output style, you can use the RTF keyword "\cs". For example, if you want to format Title field using a style already defined in your document. You have to know what is the RTF style definition number for that style (you can open rtf as plain text to find out). If that number is 15, you can put "{\cs15" in the before field edit box and put "}" in the after field edit box. When used, the Title field will be formatted using the style sheet 15 in that RTF file.
This is definitly for power user only. You need to understand RTF well to use it.
