A portable communications device, e.g., a cell phone with a simplified
user interface and easy to use keys is described. The user interface
supports book type and circular type applications. Book interface type
applications are applications in which a user is stopped from moving
beyond the last page when a next page operation is selected. In circular
applications a user is allowed to move from the last page of an
application to the first page of the application by selecting a next page
option. Regardless of the application type, in response to a displayed
page a user, in some embodiments, is presented with at most 4 options.
This allows navigation between applications, pages and selection of
actions corresponding to pages to be supported using relatively few keys,
e.g., 4 keys, thereby allowing the number of keys on the phone to be kept
small and the key size large.
