Deleting from sequence diagrams

[specious]

Apologies if this has been asked before, but I searched the forum and couldn't find it.

How do you delete a class from a sequence diagram without deleting it from the model altogether? The Help file is quite explicit about deleting elements:

Note: This does not delete the element from the model, only from the current diagram. The exception is Sequence diagrams, where an element is deleted from the model and sequence diagram at the same time.  

I can't be the first person to have dragged the wrong thing onto the diagram by mistake...

Classes don't get deleted from the model unless you remove them through the explorer window.  Deleting them from a diagram just removes the linked item in the diagram.  The class itself will still be present in the package it was originally added to.

So the documentation seems to be wrong

Maybe the help is correct for element=lifeline (delete a lifeline from the diagram and it's gone, although the underlying class is still in the model). OK, I'm grasping at straws, I'll have a go at re-wording the help  

PS Ctrl+Del will delete a selected element from a diagram and from the model at the same time.

The help files have been fixed for the next help release to reflect the issue raised in this topic.
