The execute() function runs an application. \section1 Word list related A list of words relevant to the current locale is maintained by the system. The list is held in a \link qdawg.html DAWG\endlink (implemented by the QDawg class). This list is used, for example, by the pickboard input method. The global QDawg is returned by fixedDawg(); this cannot be updated. An updatable copy of the global QDawg is returned by addedDawg(). Applications may have their own word lists stored in \l{QDawg}s which are returned by dawg().
