+\dd This flag indicates that the puzzle cannot be usefully played

+PDA platforms, this flag is used by the front end to enable
+right-button emulation through an appropriate gesture. Note that a
+puzzle is not required to set this just because it \e{uses} the

+left button, and hence can manage fine without it.)

+\dd This flag indicates that the puzzle cannot be usefully played
