This is a common question.
I've added a faq entry (2.4) with the intent of helping people with this
and realized I'm short on information.  The jist is that readline provides
this functionality.  The original readline is in C so is not part of
Java/Jython.  There is experimental realine Java classes that will
eventually add this functionality, but not yet.  For now use a shell that
can wrap the running process (Jython) and allow readline behavior.

Here's the part I'm stuck on.  I live in emacs mostly, so I've never
really ventured beyond emacs' shell mode for this.  I tried Yorick's shell
with no luck even though I was told it works for this.  I've heard Win2k
shell may do this, but can't confirm this.  Can other's help me out with a
list a shells that provide serrogate readlines?  Can anyone confirm Win2k?
Yorick?  Other shells that we could list in the faq to help others out?

tnx,
Robert
