A wildcard is a special kind of text object that can insert text from somewhere else. For instance, Sibelius has a number of useful wildcards for various page text elements (title, subtitle, composer, copyright etc). When you change the information in Score Info, the text on the page will automatically update.
The syntax for text wildcards is a backslash, followed by a dollar sign, then the wildcard label and finally, a closing backslash. Case does not matter; they can be all upper case, all lower case, or mixed case.
Sibelius also has some formatting change wildcards, which work exclusively within the Score Info dialog. The syntax for these is simply the command encased in a pair of backslashes.
Text wildcards are designed to appear on the page; as stated above, formatting wildcards (such as for bold, italic, new line etc) can only be used in Score Info.
Here is a list of the available text wildcards for Sibelius:
\$PARTNAME\ evaluates to a list of the instruments in the part, each instrument separated by a carriage return.
\$HEADERPARTNAME\ evaluates to a list of the instruments in the part, separated by a comma and all on the same line.
\$USER\ – current logged in user
\$DATELONG\ – full date in locale-specific format, e.g. “March 4, 2005”
\$DATESHORT\ – short date in locale-specific format, e.g. “04/03/05”
\$FILEPATH\ – full path to the current file
\$FILENAME\ – filename of the current file
\$FILEDATE\ – full date that the current file was last saved
\$TIME\ – current time (insert this, then zoom in and out every second!)
\$PAGENUM\ – current page number
\$NumPages\ – total number of pages (as of Sib 7.13)
Here are the available formatting wildcards for Score Info:
\n\ New line

\b\ Bold off
\I\ Italic on
\i\ Italic off
\U\ Underline on
