Entering A Deed

I am running through the Tutorials and have a question about Tutorial 1, Entering a Deed.
When it comes time to enter a deed I go to SURVEY, ENTER DEED DESCRIPTION, and you must answer a bunch of questions on the point name, bearing and lenghth.
I you make a mistake is there a way to go back and correct it? If I don't realize the mistake until much later is there a way to edit the CRD file within Carlson. Can I edit the *.crd in a notebook editor.
Thanks for the hlep.
