29: # There are two parameters controlling the action of this module:
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
36: # browser.interface is 'textual'
