The GKOS keyboard special modes and functions
 

In general, the functions below can be selected on an application level by using menues that are easy to the user. Sometimes it may, however, be useful to be able to access these special features directly on the keyboard.
 

Modes are entered by the abc-123 key that may be preceded by CTRL, ALT, SHIFT or SYMB. To exit a mode just abc-123 key is pressed (to exit Braille mode, press 3 times abc-123). abc-123 always returns to abc mode except, while in abc mode, it activates 123 mode:

      abc-123 -> 123 mode
ALT   abc-123 -> now alternative modes* are selected by typing mode name and ENTER
SHIFT abc-123 -> pointer control mode (GKOS keyboard as a pointer control = 'GKOS mouse')
SYMB  abc-123 -> <reserved>
CTRL  abc-123 -> Braille mode (raised dots code)

* these may include activating remote control of TV, MD etc., Teach Mode or even activating a national keyboard layout (remains valid even after returning by abc-123 key). Activation may also be done so that a menu appears when Alt abc-123 is pressed.
 
 

Special functions can be activated by the SYMB key that may be preceded by CTRL, ALT, SHIFT. If there is a need to return without selecting any function after SYMB, Esc can be pressed.

      SYMB  -> pick a symbol from 123 mode or shift a punctuation/special character
ALT   SYMB  -> system menu   <or alternative (programmable) symbols or phrases>
SHIFT SYMB  -> application menu
CTRL  SYMB  -> pick a Function key or a special key (F1...F12, PrtScr, Scroll, NumLock...)
 

                  - note that CAPS does not have an effect on the 123-ABC
                  function but it must be turned off before SHIFT abc-123
