<!-- ##### FUNCTION gtk_list_scroll_horizontal ##### -->
<para>
Scrolls @list horizontaly. This supposes that the list is packed into a
scrolled window or something similar, and adjustments are well
set. Step and page increment are those from the horizontal adjustment
of @list. Backward means to the left, and forward to the
right. Out of bounds values are truncated.
@scroll_type may be any valid #GtkScrollType. If @scroll_type is
#GTK_SCROLL_NONE, nothing is done. If it's #GTK_SCROLL_JUMP, the list
scrolls to the ratio @position: 0 is full left, 1 is full right.

of @list. Backward means up, and forward down. Out of bounds values are
truncated.
@scroll_type may be any valid #GtkScrollType. If @scroll_type is
#GTK_SCROLL_NONE, nothing is done. If it's #GTK_SCROLL_JUMP, the list
scrolls to the ratio @position: 0 is top, 1 is bottom.

<!-- ##### FUNCTION gtk_list_undo_selection ##### -->
