How to set the focus over a button and execute its callback withreturn

Hi anyone,

I have made a figure with the Matlab Guide. It has got various objects such as buttons. First, the trouble I have is I not always can set the focus over a certain button by pushing the tabulator key. The second problem is when a button has got the focus, i.e. it is selected, I can not execute the button’s callback by pushing the return key in the keyboard (It not work).

Can you help me?

Thanks in advance
