Operating the MC909X 2 - 45
Application These keys can be assigned to an application.
F6 and F7 keys cannot be remapped and are dedicated by the Operating System to
control volume level. When these keys are pressed, Shell.exe traps them and
displays the volume adjustment window. To get these keys to an application, call
GXOpenInput() at the beginning of the application and call GXCloseInput() at the
end of the application. This redirects all of the key events to an application, including
the
F6 and F7 keys.
Note: Other applications cannot receive any key event until GXCloseInput() is called.
For example, if the customer is using the APP1 key to run Calc.exe, this is disabled
during this period.
