Terminology
Display
The word ‘display’ refers to the 4 lines of text (not including the Header text) that are visible at the
same time in one view. You move from one display to another by rolling the roller down 4 times.
Card
A single WML unit of navigation and user interface.
Deck
A collection of WML cards that is the smallest download unit. You cannot download a single card in a
deck; you must download the entire Deck. Service developers should be aware of this, and not do a
giant application in one big Deck.
Hyperlink
A link within a document or card that allows quick navigation to another document (card).
Do element
A way of defining a binding between events (e.g. a user selection) and a task (e.g. to go somewhere).
Input element
A mark-up element that allows for interaction with the user, i.e. letting the user input textual values.
These can be used for inputs to locally stored scripts, or for parsing to the server of origin.
Prev element
Lets the application developer define what happens, when the user selects Back. In some applications it
might make more sense to jump to another card than the one that the user has just visited.
Options list
The Options list is the list of items shown when the user presses the Options soft key.
Proportional fonts
A font, in which the letters don’t necessarily take up the same amount of pixels in width. ‘W’ and ‘I’ are
good examples.
Navigation
The principle of moving between menu items, decks and cards.
