[development] how to set nid argument in views so it works as "not equal to"?

Hi, What I want here is a list of latest nodes which are in same type as current node (assuming in node/123 page). I create a node view and set some filters, fields, etc... then i go to the argument section. I choose "Provide default argument" and set to "Node ID from URL". Then I do not know how to continue so that views can load nodes which nid does not equal to the argument.... thanks :)
