5643
5644            The problem with this is that if the accelerators include
5645            keys without modifiers, such as the space bar or the

5650
5651            There is no good way of fixing this, but this

5653            key events involving modifiers (not Shift)
5654            get routed into the activation pathway first, then
5655            get propagated to the focus widget if necessary.
5656
5657            If the key event doesn't involve modifiers,
5658            we deliver to the focus widget first, thus allowing
5659            it to get "normal text" without interference
5660            from acceleration.
5661
5662            Of course, this can also be problematic: if there
5663            is a widget with focus, then it will swallow
5664            all "normal text" accelerators.
