Comment 3 for bug 726978

The thing is that this is a restriction of GTK. Key press events in entries within a window are also triggered on the window itself. So if we try to toggle pause upon Space key press, you will toggle it also every time you try to enter a space in one of the entries.

And due to the event processing order in GTK one cannot prevent the event to reach the window since that’s actually where it starts from, moving down to the lowest piece in the widget tree.

As for the Playback menu: this is surely something to consider but should be moved into a separate report.
