OTRS how to enable auto complete for To field?

have you any idea how to remove autocomplete=off in text fields of AgentTicketCompose ?
i would like to use cached email addresses in browser instead of instant database request via AJAX and spent some time to find just the piece of code!

Thus you should open AgentCustomerSearch.dtl file and comment out only one string:

        

//    Core.Agent.CustomerSearch.Init($("#CustomerAutoComplete"), $QData{"ActiveAutoComplete"});

Done!
