should display this string in \fIwindow\fR's title bar).  In this
case the command returns an empty string.  If \fIstring\fR is not
specified then the command returns the current title for the
\fIwindow\fR.  The title for a window defaults to its name.
.TP
\fBwm transient \fIwindow\fR ?\fImaster\fR?
.
If \fImaster\fR is specified, then the window manager is informed that
\fIwindow\fR is a transient window (e.g. pull-down menu) working on
behalf of \fImaster\fR (where \fImaster\fR is the path name for a
top-level window).  If \fImaster\fR is specified as an empty string

then \fIwindow\fR is marked as not being a transient window any more.
Otherwise the command returns the path name of \fIwindow\fR's current
master, or an empty string if \fIwindow\fR is not currently a
transient window.  A transient window will mirror state changes in the
master and inherit the state of the master when initially mapped. The
directed graph with an edge from each transient to its master must be
acyclic.  In particular, it is an error to attempt to make a window a
transient of itself.  The window manager may also decorate a transient
window differently, removing some features normally present (e.g.,
minimize and maximize buttons) though this is entirely at the
discretion of the window manager.
.TP
\fBwm withdraw \fIwindow\fR
.
Arranges for \fIwindow\fR to be withdrawn from the screen.  This
causes the window to be unmapped and forgotten about by the window
manager.  If the window
has never been mapped, then this command

 * also demand that the event ring be a bit bigger.  It might be wise to

 * DoubleClick modifier bit which could be set based on the clickCount of the
 * Apple NSEvent object.
