The Lucid online player screen has a menu bar (Restart | Collapse Tree | Expand Tree | Find | Sets | Best | Prune Redundants | Differences | Why Discarded | Help)
at the top and
four windows (Features Available, Features Chosen, Entities Remaining, Entities Discarded)
Features are comprised of characters (e.g. flower colour) and character states (e.g. flowers red). Entities in this key are typically species, but also subspecies, varieties, hybrids, and cultivars (collectively called taxa).
On start up only the Features Available and Entities Remaining windows will have content.
As features are selected (using the tick boxes) they will appear in the Features Chosen window, and the entities that don’t possess those features will be discarded (Entities Discarded).
notes and images attached to all features and entities.
Click on the icons (or thumbnails) to open them.
Restart – restarts the key to
the default Features Available list (you may need to refresh after restarting if the
features don’t appear).
Collapse Tree – collapses the
tree hierarchy to hide the character states. You must first click on the Features panel to select it
so that this function will work. You can also collapse the entities hierarchy if they
are in a tree.
Clicking the Collapse Tree menu button collapses/closes all features (characters and character states), not just the one selected.
Expand Tree – expands the
features to show the
submenus and character states. You must first click on the Features panel to select it so
that this function will work. You can also expand the entities hierarchy if they were in a tree.
Clicking the Expand Tree menu button expands/opens all features and states, not just the one selected.
Find – find
feature, character state or entity, depending on which panel you have selected and
what text you have entered in the search box.
Sets – selects
feature/entity sets (greyed out if no sets
are assigned in the key).
Best – once you’ve keyed out
(selected) some features and want to know where to go next, you can use Best.
This selects the next best feature to help reduce your Entities Remaining list. If the
feature suggested by Best is not suitable, you can continue to click Best to move to the next-best feature until you find a feature you can answer.
Prune Redundants – removes features and/or states that are no longer relevant, based on the species in the Entities Remaining list.
Differences – if you want to know the differences
among the Entities Remaining, click
Differences. This will calculate what features are different by showing a
pop-up window separated into two lists: Features and Differences. Select a
feature from the top drop-down menu to show how the states are different from
the list of remaining entities.
Why Discarded – if you want to know why an
entity was discarded, select an entity from the Entities Discarded panel and click Why Discarded.
This will open a pop-up window showing what feature(s) (character states) you selected and what that
entity is coded for.
Help – opens
the Lucid online player help page.
