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

System requirements for Lucid v 3.5 Key Matrix Java Applet

Operating System: 2000/XP/Vista, OSX, Linux and Solaris
System Memory: 256MB RAM or higher is recommended

Browser requirements
It is recommended that you run the key using a modern web browser that supports JavaScript and Java Applets. The following browsers have been tested:

Due to the interactive nature of the content, some browsers and pop-up blockers may prevent the fact sheets from loading. If you experience this, please set your browser or pop-up blocker to allow this content.
Please note: Windows XP Users you may also change your IE settings: open IE, go to Tools – Internet Options – Advanced, scroll down to the Security section and tick the checkbox Allow active content to run in files on My Computer. Additionally, certain settings under Tools – Internet Options Security – Custom level – ActiveX controls and plug-ins, may need to be changed.

Java information
The Lucid3 interactive key will run embedded within a web browser as a Java applet Player. Java Runtime Environment (JRE) version 1.4.2 (1.5 or greater recommended) must be installed on your computer for the Lucid3 Applet Player to run successfully. Visit the Java web site at: www.java.com to check what Java you are running and if required download and install (make sure to uninstall old versions) the latest Java Runtime Environment version. [ Please note: JRE 1.6.11 contains a bug that affects the Lucid Applet Player, please upgrade to the newer JRE version to avoid this issue].

Note to Macintosh users
OSX comes pre-installed with the JRE and is accessible using Safari. Ensure you have the latest version of JRE by running the software update utility. Internet Explorer version 5.2.3, which is the last version of IE for the Mac, does not support JRE, nor does Opera. Mozilla.org, however, has opted (at least since February 2007) to include the Java Embedding Plugin by default in all of its products (Firefox, Mozilla, or Camino browsers). This will enable them to access JRE and run the key. However, if you require the Java Embedding Plugin, see the links below for information regarding installation, compatibility and updates for the plugin. The Java Embedding Plugin does not work with Explorer or Opera.
Information and Installation instructions for the Java Embedding Plugin for Mac OSX can be found at: http://javaplugin.sourceforge.net/
To download the plugin directly, go to the Java Embedding Plugin Summary at: http://sourceforge.net/projects/javaplugin/
