SimpleButtonMorph openInWorld

This code makes a square button appear in the topleft corner

        SimpleButtonMorph new
                target: Smalltalk;
                label: 'Beep!';
                actionSelector: #beep;
                openInWorld


How do I make it go away?

Sorry if I posted to the wrong group.  If so, please tell me where is correct.

You can also evaluate the following expresions in a wokspace,

SimpleButtonMorph allInstances do:[:each| each delete].

or

| buttons |
buttons := World submorphs detect:[:each| each isKindOf: SimpleButtonMorph ] .
buttons anyOne delete.

But i also prefer Serge option, because  Morphs are directly
manipulable for a reason!

OTOH,

For cases like that I think the best is to attribute the result of "SimpleButtonMorph new..." to a variable and the just use the message delete on this variable...
