Place this in a new .cfg file in your cstrike directory.

Go into CS and type "writecfg demo" and it will appear in your cstrike folder. Erase the contents of that file and paste the script in there.

When you want to use this, type "exec demo.cfg" in console, then view a demo with the viewdemo command.

F1 will pause the demo
F2 will resume demo playback
F4 will pause the playback and go backward .01 second.
F5 will pause the playback and go forward .01 second.
F7 will skip backward three seconds in the demo
F8 will skip ahead three seconds in the demo
F9 returns the speed to 1x
F10 makes the playback speed slower, after 1/4 speed it rolls over to 4x speed
F11 makes the playback speed faster, after 4x speed, it rolls over to 1/4 speed
F12 will return your normal config, and quit the demo.

To restore your previous config in case of emergency, type "exec dback12.cfg" in console.
