class RtfFormatter(Formatter):
    Format tokens as RTF markup. This formatter automatically outputs full RTF
    documents with color information and other useful stuff. Perfect for Copy and
    Paste into Microsoft® Word® documents.

    *New in Pygments 0.6.*

        some generic font which is supposed to have fixed width.

            Name of the font used. Could for example be ``'Courier New'``
            to further specify the default which is ``'\fmodern'``. The RTF
            specification claims that ``\fmodern`` are "Fixed-pitch serif
            and sans serif fonts". Hope every RTF implementation thinks
            the same about modern...

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
