I used a very small digital recorder ( like doctors use ) for the explanation session. I then placed it by my computer's microphone and using voice to text software, automatically produced a Word document. Now I just quickly type the word I am searching for into the search field and jump right to the section of the document with the information I am looking for instantly at hand. I think finding information using a previoulsy recorded video would be time consuming. Just a thought.....
