Hardware button code name for Visual basic?

pocket

Hi there,

What are the key code names for the standard hardware buttons for Visual basic on those old standard pocket pcs? If a PDA has a directional button the left, right,up, down are the names of the buttons. So left direction button moves an image on a form.

But for home, or contacts, inbox what are those? MSDN network explains nothing about those. According to the emulator they are called softkey 1, 2, 3, 4 but that keyword isn't registered as a valid name in Visual basic.

Thank you
