Does control+S work? If not, what happens if you put your cursor in the document (click the text) and then press control+A to select all, then control+C to copy all, then switch to a non-horrible text editor program (e.g. Notepad++), put your cursor there, and then press control+V to paste the text from the other program? Then you can save it from the non-horrible program? (If on a Mac, use the Command/Apple key instead of Control.)
