The question mark "?" is used as a format modifier in order to signify that a help string is supplied. By default, the help string is displayed at the bottom of the window. The help string is either surrounded by square brackets, or an "@" character is placed in the format string to indicate that the help string is supplied as an extra argument. In addition to "?", %th (Tooltip Help) and %he (Help Location) are used to change the manner in which a help string is presented.
