lost password for document password protected in keychain

Hi & thank you for the input. I did get my password locked files opened and then made sure before I closed each document (there were 5, all with the same forgotten password) that I removed the password option in keychain - what I ended up doing was get someone that knew how to rewrite or rework the code temporarily and break the password (?) for the documents I needed, then each document was edited with "select all' and then pasted to a new page document, copied to another file, made sure there was no password associated with each of the newly created documents. Then everything was restored to it's original code. And I don't know how he did it, but at least it's done. I definitely recommend anyone locking a document in keychain to WRITE DOWN THE PASSWORD somewhere. Word has a fairly simple way to recover a password protected file, but Mac does not, which is should....and I did use apple support and several divisions tried to help me, but they didn't have a workaround to offer, although they were really nice and tried to help over a period of two days.... also, it's a good idea to use the same password for all the files you want locked. (the document that I absolutely had to recover was a 790 page book that I was editing, and then supporting documents for references, character outlines, etc.) I had 3/4 of the book on a thumbdrive, but needed the other 1/4 of the book that had been updated and that I had not updated on the thumdrive. Big mess. But now solved.
