5888
5889            a) event is delivered to a GtkWindow
5890            b) accelerators/mnemonics are activated
5891            c) if (b) didn't handle the event, propagate to
5892                the focus widget and/or focus chain
5893
5894            The problem with this is that if the accelerators include
5895            keys without modifiers, such as the space bar or the
5896            letter "e", then pressing the key while typing into
5897            a text entry widget results in the accelerator being
5898            activated, instead of the desired letter appearing
5899            in the text entry.
5900
5901            There is no good way of fixing this, but this
5902            represents a compromise. The idea is that
5903            key events involving modifiers (not Shift)
5904            get routed into the activation pathway first, then
5905            get propagated to the focus widget if necessary.
5906
5907            If the key event doesn't involve modifiers,
5908            we deliver to the focus widget first, thus allowing
5909            it to get "normal text" without interference
5910            from acceleration.
5911
5912            Of course, this can also be problematic: if there
5913            is a widget with focus, then it will swallow
5914            all "normal text" accelerators.
