the keyboard is used to traverse through a widget hierarchy,
primitive or manager widgets are grouped together into what
are known as ttttaaaabbbb ggggrrrroooouuuuppppssss. Any manager or primitive widget can
be a tab group. Within a tab group, move the focus to the
next widget in the tab group by using the arrow keys. To
move to another tab group, use KKKKNNNNeeeexxxxttttFFFFiiiieeeelllldddd or KKKKPPPPrrrreeeevvvvFFFFiiiieeeelllldddd.
Tab groups are ordinarily specified by the
XXXXmmmmNNNNnnnnaaaavvvviiiiggggaaaattttiiiioooonnnnTTTTyyyyppppeeeeresource. XXXXmmmmAAAAddddddddTTTTaaaabbbbGGGGrrrroooouuuupppp is called to
control the order of traversal of tab groups. The widget
specified by _t_a_b__g_r_o_u_p is appended to the list of tab groups
to be traversed, and the widget's XXXXmmmmNNNNnnnnaaaavvvviiiiggggaaaattttiiiioooonnnnTTTTyyyyppppeeee is set
to XXXXmmmmEEEEXXXXCCCCLLLLUUUUSSSSIIIIVVVVEEEE____TTTTAAAABBBB____GGGGRRRROOOOUUUUPPPP.
