[MonoDevelop] "Copy" key-binding on OS X

[Carl Emil Carlsen]

Hi Mono

In "Preferences/Key Bindings/Edit Binding" MonoDevelope does not  
recognise the Apple/Command key, but sees it as the Alt key.

When I try to bind "Apple/Command–c" to the Edit/Copy function, the  
window closes, apparently because it is already a key-binding for  
"close window".

How can I get to copy-paste the in good old Mac-style?
