How to use the mapping legend

The mapping legend defines the available features in the migration interface by displaying a symbol followed by a text description.

The mapping legend helps the user learn more about mapping icons, each action, and more, hidden by a map icon. On our Wizard, it is a little bookmark, as shown below:
mapping_legend
 
On the detailed mapping page, it displays as a button in the header:
legend_button
 
There is only one section, Actions. The legend contains all actions which are available for source or target fields.
