Michael,

You need to override the KeyDown() method and check for the tab key and 
do the call to MakeFocus() manually, here is a code bit that will get 
you started:

void DocInfoText::KeyDown(const char *bytes, int32 numBytes)
{
    // test for tab
    if (bytes[0] =3D=3D '\t') {
        // get parent and get next child
        BView *child =3D NextSibling();
        if (child) {
            child->MakeFocus(true);
        } else {
            child =3D Parent()->ChildAt(0); 
            if (child) child->MakeFocus(true);
                   // *** Call the view here and send Tab Message or change 
scroll location. **//
        }
    } else {
        BTextView::KeyDown(bytes, numBytes);
    }
}
 
This is not totally safe since we should check the call to Parent(), 
and you would also need to do the 'Shift-Tab' check to go the other way 
too.
