Move an agent up or down in the list with these buttons. The order of the agents cannot be changed except at the start of a simulation.
Although you can change the agent order at the beginning of any simulation, making changes while replaying a simulation will invalidate all subsequent recorded results and adjustments. For example, rewinding a simulation (or opening a saved simulation) and changing the agent order would erase it from the revision point forward. (This will not affect the saved version.) Gas Man® will ask you to confirm your intent whenever you modify a simulation during replay.
You can also context click (right click) this table on the row for an anesthetic, which wil display a menu you can use to perform several functions in the context of that anesthetic. (see Agent Context Menu).
