Hi, Dick -

You get it by clicking where there are no objects on the screen, and 
with the alt key pressed (on non-Macs, it may require a different 
control key).  It looks like...

We are in the process of producing a tutorial entirely in the Lively 
Kernel.  It should lead you carefully through each necessary step.  I 
wrote this assuming that you already knew some basics.

Back on our original web site...


... there is a tab labelled 'Interactive Tutorial'  that should guide 
you through some of the basics.  I jumped past these in order to tell 
you about our pie menus, and I guess that was a bit premature.  If 
you have not tried this, please do.  Your comments will help to guide 
us in producing the next version entirely in LK.

Yes.  We are indeed sorely cursed in this regard.  We take your 
critique and cautions as serious exhortation to do the job right, and

By the way, you will find a  link to the Lively Kernel talk at Google 
( a demo, not a tutorial)


on both our old home page,


and the new wiki one


Hope this helps.  We appreciate your patience in debugging our 
process of disclosure here.  There is more to come, and I hope that 
we can make it much more effective.
