Actually, to get at the Smalltalk tools, use the view-source key. This  
is also mapped to Alt-, if you happen to not run on the XO, while ALt- 
Shift-W brings up the regular Squeak main menu. Under help-preferences  
you can disable the etoyFriendly setting, which then brings up the  
main menu on a background left-click.

Only they can answer that. It is all the sources, yes.

We currently ship an 18 MB .sources and 600 K .changes file. So the  
condenseSources step isn't going to make much of a difference (we did  
it in April to produce EtoysV3.sources).

Not currently.
