6.4 Using Phone Buttons and Functions Keys

Now let us introduce to you another useful element in WML — the <do> element. The <do>
element is used to associate a task to a certain user interface element of a wireless device. The
task will be done if the user activates the user interface element. The mapping between a <do>
element and a user interface element depends on the actual wireless device. The WAP specification
states that the user interface element may be a softkey, a function key, a voice-activated command,
etc. In mobile phones, <do> elements are very often associated to softkeys or items in the
options menu that is brought up by pressing a softkey. To program softkeys of mobile phones,
we need to know how to use the <do> element.
The <do> element is not difficult to use. Tasks such as <go>, <prev> and <refresh> are enclosed
in the <do></do> tags. The name attribute of <do> specifies a unique name to a <do> element.

Did u know? What does the label attribute specifies?
The label attribute specifies the label to be displayed on the wireless device’s screen (if
applicable).
The number of characters in a label should be equal to or smaller than six if you want it to be
displayed nicely on different types of wireless device. If a label is too long, it may be truncated
on some wireless devices.
