How can I enter control codes, like a Return?
Switch on the option "Allow control codes" inside the "Options" menu. Now you can enter some control codes in human readable form. Type the control characters within pointed brackets: <CR>, <LF>, <TAB>, <ESC>, <DEL>, <BS>, <VT>, <FF>, <FNC3>. If you need other control codes, you can enter the ASCII value of the needed character as 3 digits within pointed brackets, e.g. <065> for A or <026> for EOF.
