What to do with typos when answering script questions?

[jsibley2]

Backspace doesn't seem to work in the console and I usually don't want to exit from the script. What do I do if I make a typo and want to correct it?

It then becomes easy to be "exited" prematurely from the script rather than having a chance to type a module name correctly.

Thanks!

I'm open to listening to any ideas you might have. I can't think of any good solutions that let you go back to a previous field in a CLI application.
