It does exist, but you currently have to edit the moi.ini file.

Close down MoI, then open moi.ini in notepad or something, you can find it here: C:\Documents and Settings\[your user name]\Application Data\Moi\moi.ini . By default the standard ones for ctrl+s = save, etc are defined there and you can add your own there directly.

But don't edit the moi.ini file with MoI still open, because it will write out its current settings when it closes.

I guess I will probably try to do a proper interface for editing these at some point.
