A comparison of the main screens of Intkey and Lucid is available at
This document contains dumps of the screens, showing the same stage of 
an identification. Numbers indicating the corresponding features of the 
two programs, and referring to explanatory notes, are superimposed on 
the screen images. The notes are reproduced below.

1. Toolbars

Intkey. Three toolbars: (a) user-definable (buttons can represent any 
operation or sequence of operations); (b) characters/identification; (c) 

LucID. A single toolbar. Definition of buttons by the user not possible.

2. Extended help for toolbar buttons

Intkey. Available in separate window via '?' button. Length unlimited.

LucID. Automatically displayed at bottom of screen. Length limited.

3. Subdivision of main window

Intkey. Main window subdivided into panes, allowing easy resizing of 
subdivisions. Default sizes of the panes are chosen for efficient use of 
screen space.

LucID. Main window subdivided into windows, making resizing cumbersome. 
Default sizes of the windows are equal.

4. Order of subdivisions of main window

Intkey. Character panes on left, taxa panes on right. This allows 
efficient use of screen space (character text is usually longer than 
taxon text).

LucID. Character windows at top, taxon windows at bottom.

5. Structure of lists

Intkey. Simple lists.

LucID. Trees.

6. Horizontal scrolling

Intkey. Horizontal scrolling of panes allows long lines to be viewed.

LucID. No horizontal scrolling - long lines are truncated.

7. Default order of available characters

Intkey. Best order.

LucID. Natural order.

8. Character selection

Intkey. Character selection causes display of separate state-selection 
window (not shown). This allows identical operation from text and image 
state-selection windows.

LucID. Character selection causes display of states in the same window, 
as branches of the tree.

9. Character images

Intkey. Accessed automatically, if available, when character is 

LucID. Accessed by clicking on 'Information' button adjacent to the 
character or state.

10. Omission of redundant words

Intkey. Redundant words are omitted from the 'Used Characters' pane, 
allowing more text to be seen without scrolling.

LucID. Redundant words are not omitted from the 'Character States 
Chosen' window.

11. Multiple states of a character

Intkey. In the 'Used Characters' pane, multiple states of a character 
are displayed on a single line.

LucID. In the 'Character States Chosen' window, multiple states of a 
character are displayed on separate lines. These lines are not 
necessarily contiguous.

12. Available/Used characters

Intkey. Used characters are displayed only in the 'Used Characters' 

LucID. Used characters are displayed in the 'Characters Available' 
window, as well as in the 'Character States Chosen' window.

13. Taxon information

Intkey. Obtained via a button in the toolbar.

LucID. Obtained via a button adjacent to each taxon name.

14. Taxon selection

Intkey. Multiple taxa can be selected in the taxa panes (which behave as 
a single list for this purpose), and any operation can be applied to the 

LucID. Only a single taxon can be selected in the taxa windows. Multiple 
selections must be made in ad hoc dialogs.

15. Number of differences

Intkey. The 'Eliminated Taxa' pane (and the 'Remaining Taxa' pane, if 
the error tolerance is non-zero) displays the number of differences 
between the specimen and each taxon, and the taxa are sorted on this 

LucID. The number of differences between the specimen and each taxon is 
not displayed, or used to sort the taxa.
