Trees and Lists

In some Lucid3 keys, features and entities may be arranged into hierarchical trees, with sub-features nested within features and sub-entities nested within entities. For example, a key to palm species may have features arranged using a morphological hierarchy (with leaf, flower and fruit features nested under appropriate headings), and entities arranged into a taxonomic hierarchy (with species nested within genera etc.).

If the features and entities in a key are arranged into trees, you may choose to display the features and entities as trees or lists by selecting the appropriate tab at the bottom of the Features and Entities panels.

Note that some operations and modes in Lucid3 work only with lists. For example, Sort Best and Ranked Match Mode require that the key is in List View, as only lists can be sorted or ranked.
