Barcodes cannot encode keyboard function (or action) keys. The reason is that function keys are unique to the hardware and are not an ASCII code. For a PC keyboard, function keys transmitted as keyboard
scan codes and have no equivalent ASCII control codes that can be coded as a barcode. However, there is a workaround. Many keyboard wedge scanners can be programmed to substitute a function key each time they scan a specified
character. Since a keyboard wedge reader uses the same data transmission standards as a keyboard, they can send a scan code representing a function key.
For example, if the application will never need a plus sign (+) in the barcode, the keyboard wedge replaces the plus sign with an F3 key. If "12345+" was scanned, it would produce the data stream "12345" followed by the
F3 key. This same approach may be used even with barcode readers attached to a serial port if a "soft wedge" program is used. This "soft wedge" is a program that takes data from a serial port and treats it as if it had come in through the keyboard. Some of these programs also allow character substitution.0 -

Hello,
You need to look at the programming / operator manual of your bar code scanner in order to find out how to replace a certain character (e.g. the "+" key as in my example) by an F8 function key.
