Gpe-what is a notification tray applet to control context sensitive help in the gpe palmtop environment that replaces the mouse-over tooltips that are not usable with the stylus commonly used with embedded devices.

when the tray icon is clicked, the system enters "help mode"; normal ui is suspended, and the next stylus tap selects the widget for which help is wanted. the help text, if available, is displayed in a small pop-up bubble.
