This is undoubtedly the coolest marking system anywhere. VoxPro markers are the answer for every user that's ever done an interview longer than a minute or recorded an entire ball game and wondered where something was in the recording. On the fly while recording, a simple tap of the letter "M" on the keyboard brings up a window that is time stamped.  You can let the time stamp be your mark or type in a quick description of what is at the mark.  Once the file is finished recording you open the Marker List for that file and see a complete list of your marks by timestamp and description.  Click on one and it takes you to that point in the recording.
