Function/Control Key Support in HID Keyboard Mode
The TriCoder, when in HID Keyboard Mode, can transmit Function, Control, Alt and Shift Keys for use with software programs that
use these keys for menus or commands. For example, when the TriCoder reads a bar code containing the Code 39 characters for SOH
(Control-A), it will transmit the corresponding function key, F1 to your computer. These "keys" are created by combining two Code
39 characters. In order to read them and have them interpreted as the correct keystroke, the bar code reader must have " Full ASCII
Code 39" reading enabled. The following chart shows the encoding scheme for both IBM and Macintosh computers.

Table A-3. C39 Keyboard Support for IBM and Mac
This chart corresponds to the small center section of keys between the main letter keys and the numeric keypad on the right of the
keyboard. If you are using MAC AND USB, in order to emulate the arrow keys, you MUST USE THE COMMANDS AS SHOWN
ABOVE. You can scan them from the FULL ASCII MENU, for example, to emulate the “Left Arrow” key on the Mac (USB) scan
the “NUL” (which represents “$U”) bar code and then the “4” bar code from the menu.
