Using the virtual keyboard service you can configure various keyboard options. You can also obtain the dynamic keyboard height.

Your application can display the virtual keyboard by calling virtualkeyboard_show() , and can hide it by calling virtualkeyboard_hide() .

To change the keyboard options, call the virtualkeyboard_change_options() function and specify the keyboard layout and Enter key text. The enumeration virtualkeyboard_layout_t lists the keyboard layouts, and the enumeration virtualkeyboard_enter_t lists the options for Enter key text. The Enter key text is automatically updated to the correct language if you change the language of the keyboard.
