BE already has this. Hit the CTRL button and BE will set the value in the Marker column to 1. Hit CTRL again, and the value will return to 0. Hit CTRL again and the Marker column values will be set to 2. Hit it again, and they return to 0. This makes it easy to find specific locations in the datalog when you go back to look at the logs. The fact that each incident of this increments the value allows you to sort the Marker column and get ALL rows that you marked as interest will sort together.
