You can also right-click the consensus sequence and select Open Sequence. This will not create a new sequence but simply let you see the sequence in a sequence view. This means that the sequence still "belong" to the contig and will be saved together with the contig. It also means that if you add annotations to the sequence, they will be shown in the contig view as well. This can be very convenient e.g. for Primer design ().
In order to preserve the history of the changes you have made to the contig, the contig itself should be saved from the contig view, using either the save button () or by dragging it to the Navigation Area.
