The reason is that in Cuis the Transcript can update immediately while 
things are running. For instance, when running

1 to: 10 do: [ :i | i print. (Delay forSeconds: 1) wait ]

you don't need to wait for execution to finish. Additionally, updates 
sent from different processes are instantly displayed in the order they 
are sent. This is useful for debugging synchronization issues. Also, 
Transcript doesn't use Morphic, or the text display machinery in Morphic 
used by the rest of the tools. Transcript can even be used without a 
running UI at all. This is very useful when working on the UI process 
and the UI framework itself.

All this means Transcript is dog simple. It can't edit text, or scroll 
or select it.

It should. Please play a bit with it, and if you don't see it updating, 
tell steps to reproduce.

Just pushed a variation of this to GitHub. Please test.

In Workspaces we have "doIt" and "printIt". "printIt" prints to the 
workspace, and usually I don't want that. But I personally do like some 
feedback on the result of the evaluation, and didn't want to add yet 
another shortcut key.

I think we'd add a preference for this. Thoughts?

I don't think it is possible, and it would be a nice addition.

Thanks!
