the GtkClist should scroll by keys automatically if it has the focus.

To make sure selected rows are visible you will want to use code like this:

 if (! (gtk_clist_row_is_visible (clist, cur_selection) & GTK_VISIBILITY_FULL))
    gtk_clist_moveto (clist, cur_selection, 0, 1.0, 0.0);


Salut, Sven
