save, apply, cancel - but what does apply versus save do?

I'm wondering about

PRChangeCommand>>buttonSpecification
        ^ Array with: self saveButton with: self applyButton with: self  
cancelButton

That puts save, apply, cancel on the design, edit, and settings panels.

But I'm wondering why save, versus apply.  What's the thought behind  
'Apply" versus just having the
save, cancel.

Apply performs the current edit operation, but does not close the edit
command. This is useful if you want to save your writings from time to
time without closing the dialog, of if you edit the design and want to
observe the changes.

Ah, well the interesting side effect. is with wikiserver if you tap  
apply then tap save we end up marking the
PRPage as being dirty then our auto-save feature kicks in at some  
point. However the save occasionally fails because there is an  
outstanding
WAAnswerHandler instance that is servicing the other apply or save  
that is in progress.


I guess I''ll change things so that we only allow the  save/cancel  
because I've had folks think they have to do apply then save, or  
confused why there
is apply & save.
