Function keys are provided as shortcuts to enable you to quickly navigate through the application. For example, the function key to view the Main Menu is F10.
Navigating through the CUI mobile terminal screens is primarily based on the "Arrow" keys for scrolling UP or DOWN the screen. The CUI mobile terminal operates mainly on the basis of the function keys F1 through F12, which provide context-driven functions.
The F1 key brings up the contextual help screen. In most instances, F3 is "Go", and F10 brings up the main menu.
The F1 function key provides instant access to contextual help. It provides the complete list of available functions with respect to the various function keys, in any given context.
For example, when the F1 key is used during login, the F3 and F10 options are displayed. The F3 function key submits the login information, and the F10 key exits the application, while the ENTER key returns you to the previous menu.
