I've attached a "demo.cfg" file to this post. What it does is allows you to control things (speed mostly) in an easy to use way.
For 1.1
1. Put this into your base folder (base folder found where tremulous.exe or similar is)
2. Open Tremulous 1.1
3. Type in "/exec demo.cfg" while watching a demo
4. Press + (numpad) for a list of help
For GPP
1. Put this into your base/gpp folder (base/gpp folder found where tremulous-gpp.exe or similar is)
2. Open Tremulous GPP
3. Type in "/exec demo.cfg" while watching a demo
4. Press + (numpad) for a list of help
WARNING: THIS WILL OVERWRITE MOST BINDINGS, IF YOU DON'T HAVE TEAM CONFIG FILES, YOU WILL LOSE YOUR BINDS!
