It seems the only one of my demo binds that works anymore is show normals. I bound that to my F8 key. I also had binds to regular keys for slowing down or speeding up the demo. But now, any time I hit a button other than F8, it stops the demo and dumps me back to the main menu. Does anyone know how to slow down the playback of a demo. NOT an avi that someone made.

Give a look at the binds at the bottom: https://pastebin.com/pQX9kMvA

The first thing you need to do (so that pressing a key doesn't interrupt your demo playback) is:

com_cameramode 1

Then, if you want a simple setup for slowing down/speeding up:

3 "timescale .25"
4 "timescale .5"
5 "timescale 2"
6 "timescale 3"
7 "timescale 4"
8 "timescale 8"
9 "timescale 16"
= "recorddemo"

Adjust to suit your tastes - but, I find 16x playback is a good fast forward speed to skip ahead several minutes, .5 is good for slowing down when you get close to the part you want to view/record, and, .25 is a good "slow motion" speed if you want to either emphasize a dramatic moment, or, simply take a close look at what's going on.

But that first command, is the important one, so you don't have to keep re-loading the demo and starting over every time you hit a wrong key by mistake!

That must be the key. I haven't tried this yet, but looks like it will work. Thx
