This option is only available when a single channel is selected. Invocation creates a copy of the selected channel. Its name is set to that of the original channel, to which an integer is appended to ensure uniqueness (this value can be incremented if required). Its initial state is Added, and its other properties are as per the original channel. It is listed immediately after the original channel and is selected.
Note that, if you clone a default channel, the newly-created clone is not marked as a default.
Note also that, if you attempt to create a new channel, and the number of configured channels is the same as system configuration setting MaxChannels, a warning is displayed, advising that the maximum number of channels that can be configured has been reached.
