   30: #
   31: # browser.interface - if this is 'textual', it overrides the second parameter
   32: # and goes to screen reader PDA mode
   33: #
   34: # environment.remote - if this is 'on', the routines controll the remote
   35: # control, otherwise they render the main window controls; ignored it
