5896            key events. The normal sequence is:
5897
5898            a) event is delivered to a GtkWindow
5899            b) accelerators/mnemonics are activated
5900            c) if (b) didn't handle the event, propagate to
5901                the focus widget and/or focus chain
5902
5903            The problem with this is that if the accelerators include
5904            keys without modifiers, such as the space bar or the
5905            letter "e", then pressing the key while typing into
5906            a text entry widget results in the accelerator being
5907            activated, instead of the desired letter appearing
5908            in the text entry.
5909
5910            There is no good way of fixing this, but this
5911            represents a compromise. The idea is that
5912            key events involving modifiers (not Shift)
5913            get routed into the activation pathway first, then
5914            get propagated to the focus widget if necessary.
5915
5916            If the key event doesn't involve modifiers,
5917            we deliver to the focus widget first, thus allowing
5918            it to get "normal text" without interference
5919            from acceleration.
5920
5921            Of course, this can also be problematic: if there
5922            is a widget with focus, then it will swallow
5923            all "normal text" accelerators.
