Abstract: Modification of the presentation of page appearance, page navigation flow, and other aspects of the user experience of an online shopper navigating the virtual shopping cart and checkout pages of an online store is achieved without compromising the security of checkout processing. The modification may include customization, and various configuration and customization tools may be employed. The online shopper experiences continuity between unsecured-connection pages presenting items for purchase and secured-connection pages presented for checkout processing. In one embodiment, page navigation flow is modified using continuations implemented using a relatively small stack to save information relating to the flow. In another embodiment, a page designer enables a dynamic version of a page specification program to be generated, such as by way of a page customization interface. Partial evaluation is employed to generate a version of the program that is executed at request time.

Abstract: A data entry apparatus (10) receives a first character key from a keypad (12). A set of characters associated with the first character key is displayed. A second character key from the keypad (12) is received, wherein a second set of characters is associated with the second character key. A character from the first set of characters is combined with a character from the second set of characters. A set of alternative n-grams is displayed, derived from the step of combining, in descending order based on a probability of frequency of use in a given language. When an alternative n-gram is detected as being actively highlighted, the n-gram is locked to create a locked n-gram and characters associated with subsequent character keys vary in their combinations with respect to the locked n-gram.

Abstract: A method and apparatus for implementing a graphical user interface keyboard (10) and a text buffer (12) on an electronic device. A character that is active upon pointer-up is accepted as a text character, even though the character that is active upon pointer-up is different from a character that was active and inserted in the text buffer (12) upon pointer-down.
