By default, the Slave Token is created on whatever layer the selected Master Token is not on. So, if your Master Token is on the GM Layer, it will make the Slave Token on the Objects Layer and vice versa. You can specify --push when you run this command and if the Master Token is on the Objects Layer, it will push it up to the GM Layer and create the Slave Token on the Objects Layer. (see AutoPush below) !bump -- swap the Master Token and Slave Token. You can run this with either selected. It will apply the operation to all selected tokens that are part of a Bump Master/Slave pair. If you have the AutoSlave setting on, using this command on a token that isn't in Bump yet will slave it for you. !bump-config -- An interface to setting the configuration options for Bump. More on those in a bit... It looks like you have a space between !bump and -slave. There shouldn't be a space there. !bump-slave --push Also, if you have 'autoslave' turned on, then the only command you should need is: !bump
