+.PP
+\fBTk_HandleEvent\fR is a lower-level procedure that deals with window
+events. It is called by \fBTcl_ServiceEvent\fR (and indirectly by
+\fBTk_DoOneEvent\fR), and in a few other cases within Tk.
+It makes callbacks to any window event
+handlers (created by calls to \fBTk_CreateEventHandler\fR)
+that match \fIeventPtr\fR and then returns. In some cases
+it may be useful for an application to bypass the Tk event
+queue and call \fBTk_HandleEvent\fR directly instead of
+calling \fBTcl_QueueEvent\fR followed by
+\fBTcl_ServiceEvent\fR.
+.PP
+This procedure may be invoked recursively. For example,
+it is possible to invoke \fBTk_HandleEvent\fR recursively
+from a handler called by \fBTk_HandleEvent\fR. This sort
+of operation is useful in some modal situations, such
+as when a
+notifier has been popped up and an application wishes to
+wait for the user to click a button in the notifier before
+doing anything else.
