Last time I played Gettysburg, a few years back now, I was able to use the F6,F7 and F8 keys to adjust the replay speed. This is not working for me now in my latest game. Has this function been disabled? It really was a time saver.
It should work for a replay but not with 'On Map display' enabled.
Quoting from the latest documentation available from the JTS website (
https://www.johntillersoftware.com/Updates.html):
"During the replay you can use the following Hot Keys.
F5 – slow down the battle replay.
F6 – play a battle replay at default speed.
F7 – speed up the battle replay.
F8 – play a battle replay at maximum speed.
Esc - will terminate the replay.
[...]
It doesn't matter what your current setting is, your opponent's setting during his
play will determine whether you see the Dialog or the On Map Results in the
replay."
