Tags are customisable labels or keywords that offer another option for organising your references alongside groups.
To create a new tag:
The Tag will appear under My Tags in the side navigation.
To add a Tag to a reference drag and drop the reference onto the Tag label. The colour of the tag will then be added to the reference. Several tags can be added to the same reference.
To view all the references tagged with a specific tag, click on the tag label.
