I doubt that the keyboard shortcut feature is designed to work with a single character as the shortcut. Try to involve some modifier key, e.g. <Ctrl>, <Alt> or <Super> similarly as the predefined shortcuts.

The shortcut § works fine, but if I press the letter "s" on my keyboard, Guake is opened as well. What do I expect: > That the letter s writes an s. What's happening: > Everytime I press "s", guake opens, but I can't use the letter "s" anymore. I had to map a different shortcut (Maj §) and the "s" works fine.
