Hi Toni,
first: it seems to me you always title your threads with "I need help"... Can you be just a little bit more descriptive? It really helps to get the topic from the title!
2nd:
Right-click the controls, advanced->keyboard navigation (or properties and according tab), select assigned key for the control...
Best regards,
GerdW
