Is there a different way to delete parameters in the Class Properties dialog box?

Users,

I have created several classes with methods that have no parameters.

I am re-editing the classes to include parameters.

 

I have accidentally clicked the New Parameter button in the Class Properties
several times now.

The only way I have found to delete the new parameter is to edit the long
string in the Class Diagram.

Is there a different way?

 

I've noticed that the Parameters box allows left clicking the parameter and
the only allowed options are Move Up and Move Down.

Can we add a delete option?
