the f2 key is labeled in the menu and is redirected to a methode in the form. there i look to the status of the data form. If this dataform is in normal status then i launch the search methode on the form if the form is in modify status than i lauch the search methode on the object with

LOCAL loSearchObject

IF TYPE("_Screen.ActiveForm.ActiveControl")=="O"

loSearchObject = _SCREEN.ACTIVEFORM.ACTIVECONTROL

IF PEMSTATUS(loSearchobject,'searchformmethode',5)
_screen.ActiveForm.activecontrol.searchformmethode
ENDIF
ENDIF

and that is sometimes working sometimes not....
