The Sequence Editor's Channel Settings dialog allows you to set various properties of a channel in your sequence, such as its name, color, unit ID and circuit ID.
You can access the Channel Settings dialog by clicking on the channel's button, or right-clicking and selecting "Change Channel Settings" from the popup menu.
Not all settings are available for all channel types; for example, X10 controllers do not use circuit IDs, and only channels representing subsequences can specify the name of a sequence file. The controls for unavailable settings will be greyed out.
The Channel Configuration screen allows you to do the same sort of things as the Channel Settings dialog, but can be used on all of the channels in your sequence at the same time.
