非焦点窗体上的 C#/WPF 热键（如 launchy）

Is it possible to catch a hotkey (eg. Ctrl+Space) from a not focused form, to make it appear whenever someone uses this specific hotkey ; And without having to register this hotkey on the registry. A similar event can be noticed in the application "Launchy".

谢谢

语言：C# (WPF) // 操作系统：Windows
