Button Bar

The Lucid button bar, located above the four panes and below the menu, looks like this:

Some of the most commonly used buttons are:

Button	Name	What itdoes
	Restart Key	Starts the key from the beginning. Used if you wish to identify a new entity using the same key or if it is quicker to start again on the specimen that you have been trying to identify.
	Collapse selected list	Collapses the list of entities or features, depending on which quadrant (pane) of the key you are in.
	Expand selected list	Expands the list of entities or features, depending on which quadrant (pane) of the key you are in.
	Find feature/entity...	Opens a search box that you can type in to find a feature or entity (depending on what side of the key you are on). Especially useful for large keys.
	Feature Thumbnails	Displays or hides all of the feature thumbnails. Provides a visual method for identifying plants but restricts your view of the feature list.
	Entity Thumbnails	Displays or hides the first thumbnail for an entity.
	Subsets	Most of our keys have groups of features available. This button will give you options to choose restricted sets of features – e.g., characters that only apply to non-flowering plant material, and expert, novice, and non-identification data subsets.
	Best	Highlights the feature that will provide the most discriminating identification based on the entities remaining. ‘Best’ is useful when you have only a few similar taxa remaining.
	Previous Best	Allows you to navigate back through your ‘Best’ choices once you have used ‘Next Best’.
	Next Best	Takes you to the next best feature(s).
	Help	This button accesses the extensive help files preloaded within each key by the Lucid software developers.
