Abstract: Methods, apparatus, and computer program products for controlling a user's interaction with a keyboard of a multi-application electronic device such as a personal digital assistant. In one embodiment, a keyboard usage statistic for the user is determined and compared with a usage limit. Responsive to the comparison, an input mode capability of the device may be altered by throttling keyboard input to a first application such as a text input application while permitting unlimited input to a second application such as a speech input application. Altering an input mode capability may include at least one of: disabling a keyboard function, enabling an alternate input mechanism, and instructing the user to use the alternate input mechanism.

Abstract: A technique, system, and computer program for quickly and efficiently selecting or deselecting a spatially-related group of objects using a single selection or deselection operation, while preserving the ability to select or deselect individual items within a group or subgroup. A new set of graphical control objects is defined, any of which will graphically indicate the members of the group with which it is associated without requiring a textual explanation. Alternatively, a control object such as a slider bar may be used, where the technique of controlling the selection status of the group is defined for the slider bar in a novel manner.
