For example, you can include the name of a data file in the title of your plot as follows
    query \filename "File to read from?" ("data.file")
    open \filename
    read columns x y
    draw curve
    draw title "data from \filename"
Within math strings (ie, between matched dollar-signs), these synonyms are disabled, and only the mathematical symbols and Greek letters work.
