Fill another field with value of a search help without an ENTER

Hi ,

This problem you will find everywhere in SAP.

You open a SearchHelp, select a value and the value is placed in the input-field. Only after an ENTER the text-field next to the input-field is being filled.

Do you know how I can change this in an customer-specific transaction, so that the text-field and input-field are filled without an ENTER ??

Kind regards,
