To access your preferences, you can
  • select the star icon in the upper right hand corner, 
  • use the F5 key to open the My Preferences window, or
  • right-click on screen to open a selectable drop down menu to access My Preferences (F5).
The last two options are particularly helpful if using the XL screen size option and switching between devices of differing screen sizes, where the star icon may not be immediately accessible on a smaller device screen.
