It's one thing to request more Emacs-like functionality in DrScheme, and 
another to assert that you can't work through SICP without it. You can 
work through SICP in Notepad -- arguably, working through any learning 
sequence in a manner where hasty changes are discouraged is actually 
better. I find DrScheme's search function awkward enough that I use it 
infrequently, but it's pretty low on my wish list. And, like Noel, I 
don't use a debugger. For code using `random', `random-seed' is useful 
in development mode. --PR
