These keys can have an application assigned to the function value and have an alpha value
assigned when used with the ALPHA function key.
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.
Press and release the blue function key to activate the keypad alternate functions (shown
on the keypad in blue). The keypad LED lights.
Press and release the CTRL key to activate the keypad alternate CTRL functions. The
keypad LED lights.
Press and release the ALT key to activate the keypad ALT (alternate) functions. Press and
release the ALT key again to return to the normal keypad functions.
The default keypad mode is the num-lock (number lock) mode. Press the orange ALPHA key
to de-activate the num-lock mode and to access the alternate ALPHA characters (shown on
the keypad in orange).
Press and release the SHIFT key to activate the keypad alternate SHIFT functions. Press and
release the SHIFT key again to return to the normal keypad functions.
