Audio Bookmarks

[Gunnerman8]

I was recently told by a Macbook Pro user that it was possible to record voice notes while typing at the same time. While that is simple enough, the user then said that they were able to type in a keyword in their typed notes, and they would be taken not only to the word itself in their notes, but also to the exact time in the audio recording that that word was typed. For example, were I to start recording and type the word "cardiology", I could later search for "cardiology" and my results would take me to the point in my audio recording that I typed that word. Does anyone have any information as to how this is possible? Unfortunately, I didn't get the name of the program(s) that were being used. Thank you very much!
