Yes, but bear in mind that the more advanced systems are perfectly capable
of figuring out which widget is next in some sequence and forging the
events to move focus to that widget. The application is still operated
"with a mouse", but that doesn't mean that the software representation of
the mouse has to be operated by the user. This is only needed because of
limitations in controlling and communicating with the widget set, but it
has been done. 

For Gtk, I think the main thing at the moment is to remember to separate
interface and implementation. If Tab and Shift-Tab move between controls,
that's good, but make the ordered list of controls itself available so
that external agents can move among the same sequence without having to
synthesize Tab keystroke -- or worry about what Tab does in a GtkText
