I like to play long campaigns and, like you, don't really have the time to watch the full replays on normal mode. I use F7 to increase replay speed to a level where I can still work out what's going on and where but not so fast that things become a blur. A typhoon turn will take about 5 to 10 mins to watch like this.
I believe there are several speed levels by pressing the F7 multiple times, or at least it has always seemed that way to me. :). The full list of speed keys from the manual are
F5 – slow the speed of the A/I processing.
F6 – return A/I processing to normal speed.
F7 – increase the speed of the A/I processing.
F8 – put the A/I in the highest possible processing mode (use F6 to return to normal).
