Web Browser Navigation

Web navigation uses the Navigation cluster, the OK button, softkeys and Line buttons, as illustrated in Figure 20.

Figure 20:  Navigation Keys and Buttons

Web screen navigation works as follows:

• One link is permitted per line. The link can be activated in one of two ways - pressing the right Line button, if available and if associated with a particular display line, or pressing the OK button if the line is in focus or highlighted.
• Line buttons, if available, or the OK button in the middle of the navigation cluster are used to select an option.
• Line buttons, if available, or the OK button in the middle of the navigation cluster are used to focus on a text entry box to allow entry of text.
• The WML card author can use the softkeys on the bottom of display for navigation as appropriate. The default softkeys labels are Home, Refresh, and Stop. The default softkey labels are always presented and are represented by icons. The More softkey is assigned to the fourth key position, and will only be displayed if the Web author defines more than one softkey. The Web author can define additional softkeys and softkey labels. Additional softkey labels (if defined) are assigned to the initial softkey label positions (beginning with Softkey 1). Default softkeys will be displayed when a page error is displayed. Figure 21 shows the default softkeys. Figure 22 shows how author-defined softkeys take precedence over the default softkeys.

• The Left navigation button takes the user to the previous card. The Right navigation button takes the user to the next card only if it is available in the history stack.
• The Home softkey takes the user to the initial home Web page as conveyed in the settings.
• The Refresh softkey reloads the same page on the screen.
• The Stop softkey always displays as a default softkey. The result of pressing Stop depends on the state of the display at that time that softkey is pressed, as follows:
• If a new page is loading, the user receives an error message and the preceding page displays.
• If a new page is not loading and no WML page has been received, nothing happens. The screen does not change, no error message displays, no error tone sounds.
• If a new page is not loading, but a portion of the WML page has been received, the screen is updated with whatever information has been received.
• Avaya recommends that the page author not include softkeys that are redundant with the default softkeys.
