Openwave Browser Proper ties
The following properties are unique to the Openwave browser. Capitalise on these to enhance usability. Use the Openwave UP.SDK 4.1 or WAP browser phone to test applications using these features.
■A label for the highest priority action is viewable and accessible from all cards.
The <do type="accept"> label is displayed on the screen and accessed by pressing the primary softkey (the right softkey in the template).
■A label for the secondary actions is accessible from a second softkey.
The <do type="options"> label is mapped to the second softkey (the left softkey in the template) and may require one or more keystrokes to select (depending on the number of <do type="options">).
■Each phone has a fixed key mapped to backward navigation.
Back functionality, <do type="prev">, is always available from a fixed key on the keypad. The default is the last card in the history if no other location is specified. This key may be shared with a Clear key in entry queries.
■Phones support the ability to select an item from a numbered list.
Numbers corresponding to <option> items precede each menu item.
