Event after Dict-SearchHelp

Hi All,

I need to perform some action just after selection in standard search-help on SELECTION-SCREEN with PARAMETERS.

But I get the event AT SELECTION-SCREEN ON BLOCK myblock. only after I press [Enter].

Can somebody tell me which event shall I use if I need to process something after selection in search-help? Or it is the only way to use .. VALUE-REQUEST FOR .. with making and calling search-help by yourself.

Thanks.
