Just about every element in Poser, whether it be an actor, prop, camera, channel, or what ever, has an internal name. For example in the case of a rotateY channel the internal name is usually "yrot", though it can be anything you like. The first part of a channel is a line that containes two elements, a channel type which tells poser what the channel does followed by a channel name. Then somewhere under that is the "name" line which determins the name displayed on the channels dial. You can make an arbitary choice of channel name and dial name, but you should not change the channel type.

                rotateY yrot -channel type and name

                        name My name for this dial -Dial name
