ido: how to reset a C-SPC filter?

[Stefan Vollmar]

Hallo,

I have just started using ido - a great package! This is probably a  
very simple question and I am sorry if I have overlooked the answer in  
the documentation: to restrict the list of files after a first  
filtering one can use C-SPC. How can I reset that filter? The  
documentation mentions C-@ - does this have the same effect as C-SPC?  
In case this is the shortcut I am looking for - unfortunately, C-@  
will not work on a German keyboard (MacOS X) and I that case I would  
have to remap it.

Many thanks in advance.
Warm regards,
 Stefan
