How I got this (in full):

* think of places where I've seen text entry fields.
* remember the Message Names browser.
* open one up
* test the widget. Figure it's good enough for an example.
* open a browser on the MessageNames class
* locate its initialization protocol
* look first at method #inMorphicWindowLabeled:, note that it just 
calls #inMorphicWindowWithInitialSearchString:
* look at method named #inMorphicWindowWithInitialSearchString:
* look down a bit to where it constructs the PTM
* copy the text to a workspace.
* do it after adding the "openInHand"
* see it blow up on #searchString (which is a pluggable selector in my 
Workspace code)
* replace the model callbacks in the Workspace code with nil (and hope 
that that doesn't blow up)
* try it again.
* note that size is too big.
* open up halos, size it to what looks like a single line.
* open up inspector from halo
* type in expression "self extent" in inspector and evaluate it.
* Copy that to my workspace and add the extent: call.
* try it again
* copy to mail message

All of which looks much more complex than it really was.

The alternative is to make a version of a text entry field that works 
the way you want and get it added to Squeak. There have been several 
people who have made these in the past. Look at
http://minnow.cc.gatech.edu/squeak/1576 for some of these.

If I were going to make one of these I'd probably try to construct 
something out of a TextMorphForEditView, a TransformMorph, and a
