To launch Show My Homework, give the command βStart SMHWβ - use the letters rather than saying the name in full.
To open the To Do screen, use the command βStart Homework in SMHWβ.
Other screens that can be opened are:
Upcoming (shows your To Do list or Dashboard
Overdue (shows your overdue tasks)
Timetable
