Could you tell me where I can find these preferences? I looked and looked
but have no idea where they could be.

Also, when in 'show code textually' mode, how do I save what I've written?
I tried doing alt-s which asked me for my initials, and then it seemed to
work. However, on reverting to tile mode, it said it would lose the changes
it made. I assume this means that there is no way of getting back to tile
mode with the changes updated (even though the change might have been
simply changing a value from say 5 to 10). You'd said "Once you start
changing a script (method in normal Squeak parlance) textually, it's best
to stay in text mode for that script" but from what I can see, you don't
really have a choice, you HAVE to stay in text mode. Am I correct?
