If ReplayMod is recording while you are playing, setting a marker with "M" will leave a mark at that time point, helping you find that spot when you go and view the Replay file later.
The F5 key still works when you are reviewing the Replay file, which means you can render three camera angles (one of them reversed) from a single path.
