How to use the key

Lucid online player tips

The Lucid online player screen has a menu bar (Restart | Collapse Tree | Expand Tree | Find | Sets | Best | Previous Best | Next Best | Prune Redundants | Differences | Why Discard | Help) and 4 windows (Features available, Features Chosen, Entities Remaining, Entities Discarded).

On start up only the Features available and Entities Remaining windows will have content, as features are selected (tick box) they will appear in the Features Chosen window and those entities that don't possess those features will be discarded (Entities Discarded).

There are notes icon notes and image icon images attached to all features and entities, click on the icons to open.

Restart – restarts the key to default Features list (you may need to refresh after restarting if the Features don't appear)

Collapse Tree – collapses the Feature to show the states, you must click on the Features panel to select it and this function will then work, you can also collapse the Entities if they were in a tree (in full version of player this would collapse/close all Features and states not just the one selected)

Expand Tree – expands the Feature to show the states, you must click on the Features panel to select it and this function will then work, you can also collapse the Entities if they were in a tree (in full version of player this would expand/open all Features and states not just the one selected)

Find – find Feature/State or Entity, depending on which panel you have selected

Sets – selects Feature/Entity sets (greyed out if not sets assigned)

Best – once you've used keyed out some Features and want to know where to go next you can use Best, this selects the next best Feature to help to reduce your Entities Remaining list, if this Feature is not suitable you can use next best or previous best, otherwise select your Feature, note if you click best again it will recalculate based on what Entities remain

Previous Best – selects the previous best Feature, used in Features panel

Next Best – selects the next best Feature, used in Features panel

Prune Redundants – this feature has not yet been implemented on this version of the player, used in Features panel

Differences – if you want to know the differences between the Entities Remaining, select an Entity and click differences, this will calculate what Features are different, the window is broken into 2 boxes: Different Features and Differences, click on one in the top box and it will list the Entity and the states that are different, note you cannot select a Feature from this box, you will need to close the window to make a selectionwhy discard

Why Discard – if you want to know why an Entity was discarded, select and Entity from the Entities Discarded panel and click Why Discard, this will then open a window showing you what Feature state you selected and what that Entity is coded for
