+	   key events involving modifiers (not Shift)
+	   get routed into the activation pathway first, then
+	   get propagated to the focus widget if necessary.
+	   
+	   If the key event doesn't involve modifiers,
+	   we deliver to the focus widget first, thus allowing
+	   it to get "normal text" without interference
+	   from acceleration.
+
