# There are two parameters controlling the action of this module: |
|
# |
|
# browser.interface - if this is 'textual', it overrides the second parameter |
|
# and goes to screen reader PDA mode |
|
# |
|
# environment.remote - if this is 'on', the routines controll the remote |
|
# control, otherwise they render the main window controls; ignored it |
|
# browser.interface is 'textual' |
