1. A method for panning and zooming a displayed image on a display screen of a handheld electronic device using an auxiliary user input device on the handheld electronic device said method comprising:
- displaying an image on the display screen of the handheld electronic device that is both pannable and zoomable using the auxiliary user input device;
toggling between panning and zooming modes that respectively pan and zoom the displayed image by successively actuating the auxiliary user input device on the device;
said auxiliary user input device being a trackball at least rotatable up-and-down and right-and-left relative to the handheld electronic device and said trackball is press-actuable for toggling between the panning and zooming modes;
requesting display of menu options of user-selectable actions associated with the displayed image responsive to actuation of the auxiliary user input device;
displaying an abbreviated menu having a short list of menu options which is a subset of a full menu of options of user-selectable actions available relative to the displayed image and the user-selectable actions of said short list of menu options having been assessed a higher probability for being user-selected than at least a portion of the user-selectable actions of the full menu of options that are not included in said short list of menu options, and said short list of menu options includes an option for at least one of panning and zooming the displayed image; and
said short list of menu options comprising a default-designated option for one of panning and zooming the displayed image in dependence upon past activity performed relative to the displayed image whereby panning is the default-designated option when the mode immediately before was a zoom mode and zooming is the default-designated option when the mode immediately before was a pan mode.

6. A handheld electronic device programmed to pan and zoom a displayed image on a display screen of a handheld electronic device using an auxiliary user input device said handheld electronic device comprising:
-
the display screen on which an image that is both pannable and zoomable is displayed; the auxiliary user input device capable of both panning and zooming the image; a keyboard located below said display screen and configured to accommodate textual input to the handheld electronic device; a microprocessor having a control program associated therewith for controlling operation of said handheld electronic device, said control program configured to toggle between panning and zooming modes that respectively pan and zoom the displayed image by successively actuating the auxiliary user input device; said auxiliary user input device including a trackball at least rotatable up-and-down and right-and-left relative to the handheld electronic device and said trackball is press-actuable for toggling between the panning and zooming modes; said control program further configured to request display of menu options of user-selectable actions associated with the displayed image responsive to actuation of the auxiliary user input device, and, based on said actuation of the auxiliary user input device, the microprocessor displays an abbreviated menu having a short list of menu options which is a subset of a full menu of options of user-selectable actions available relative to the displayed image and the user-selectable actions of said short list of menu options having been assessed a higher probability for being user-selected than at least a portion of the user-selectable actions of the full menu of options that are not included in said short list of menu options, and said short list of menu options includes an option for at least one of panning and zooming the displayed image; and said short list of menu options comprising a default-designated option for one of panning and zooming the displayed image in dependence upon past activity performed relative to the displayed image whereby panning is the default-designated option when the mode immediately before was a zoom mode and zooming is the default-designated option when the mode immediately before was a pan mode. - View Dependent Claims (7, 8, 9, 10)

11. A computer program product for a handheld electronic device comprising a user interface including a display and a keyboard having a plurality of input keys with which letters are associated, the computer program product comprising:
-
a storage medium; and an operating system module residing on the storage medium and operative to run an application on the handheld electronic device, and thereby cause an image to be displayed on the display and said operating system module further operative to toggle between panning and zooming modes that respectively pan and zoom the displayed image by successively actuating an auxiliary user input device, and said operating system module is further configured to display menu options of user-selectable actions associated with the displayed image by actuating the auxiliary user input device, and, based on said actuation of the auxiliary user input device, said operating system module displays an abbreviated menu having a short list of menu options which is a subset of a full menu of options of user-selectable actions available relative to the application and the user-selectable actions of said short list of menu options having been assessed a higher probability for being user-selected than at least a portion of the user-selectable actions of the full menu of options that are not included in said short list of menu options; said auxiliary user input device is a trackball that is at least rotatable up-and-down and right-and-left relative to the handheld electronic device and said trackball is press-actuable for toggling between the panning and zooming modes; requesting display of menu options of user-selectable actions associated with the displayed image responsive to actuation of the auxiliary user input device; and
displaying an abbreviated menu having a short list of menu options which is a subset of a full menu of options of user-selectable actions available relative to the displayed image and the user-selectable actions of said short list of menu options having been assessed a higher probability for being user-selected than at least a portion of the user-selectable actions of the full menu of options that are not included in said short list of menu options, and said short list of menu options includes an option for at least one of panning and zooming the image;said short list of menu options comprising a default-designated option for one of panning and zooming the displayed image in dependence upon past activity performed relative to the displayed image whereby panning is the default-designated option when the mode immediately before was a zoom mode and zooming is the default-designated option when the mode immediately before was a pan mode.
