You want to make multiple groups. Then you can assign a key to enable or disable a group. I'm happy to answer your questions, but this is pretty basic stuff that you should be able to find in the Girder help file or the Girder forums much quicker then posting here. If you can't find an answer though, don't be afraid to ask. I'm a newbie to Girder my self in terms of its advanced scripting capabilities... It can do a lot and there is a lot to read.
