Function/Control Key Support
The RF Laser can also transmit key sequences for function, control, alt (command and option keys on Macs), cursor and shift keys, for ease of use with the many software packages using these keys for menus or commands. You can include these codes in other bar codes, or you can scan these “keystrokes” into your Preamble or Postamble in order to add them to every scan from your reader. You must have Full ASCII Code 39 enabled on your reader (this is the default setting). Scan the corresponding bar code (or pairs of codes for Pg Up, Pg Dn, Home, etc) from the Full ASCII menu to emulate the chosen key.
