lower — Change a window's position in the stacking order
lower window ?belowThis?
If the belowThis argument is omitted then the command lowers
window so that it is below all of its siblings in the stacking
order (it will be obscured by any siblings that overlap it and
will not obscure any siblings).
If belowThis is specified then it must be the path name of
a window that is either a sibling of window or the descendant
of a sibling of window.
In this case the lower command will insert
window into the stacking order just below belowThis
(or the ancestor of belowThis that is a sibling of window);
this could end up either raising or lowering window.
All toplevel windows may be restacked with respect to each
other, whatever their relative path names, but the window manager is
not obligated to strictly honor requests to restack.
lower, obscure, stacking order
