+	   c) if (b) didn't handle the event, propagate to
+	       the focus widget and/or focus chain
+
+	   The problem with this is that if the accelerators include
+	   keys without modifiers, such as the space bar or the 
+	   letter "e", then pressing the key while typing into
+	   a text entry widget results in the accelerator being
+	   activated, instead of the desired letter appearing
+	   in the text entry.
+
+	   There is no good way of fixing this, but this
+	   represents a compromise. The idea is that 
+	   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.
+
+	   Of course, this can also be problematic: if there
+	   is a widget with focus, then it will swallow
+	   all "normal text" accelerators.
