[toronto-lisp] Fwd: Development helpers

[Aleksandar Matijaca]

Thank you all for the suggestions. Half the battle for the lowly
developer is making the development environment comfortable so that
one can concentrate on learning and building stuff and not fighting
the development environment.

If you are using LW, then it appears that most LW'ers don't use the listener in the way you intend to, and there are ways to do the same thing in LW that are more convenient (already mentioned).

Likewise, the listener is a stream buffer - just use the scroll bar to go backwards, position your cursor on a line and hit RETURN to bring it down to the current prompt.  Some of that stuff may be documented in the LW User Guide.
