In embedded widgets this can cause problems, so this call can be used to toggle it on or off as needed. The default state of the module is for the function to be disabled. Parameters ---------- val : bool If True, set_term_title() actually writes to the terminal (using the appropriate platform-specific module). If False, it is a no-op.
