The key consists of a series of windows that
can be opened, moved and closed at will.
The characters available relate to habit, bark, leaf, fruit, seedling, flower,
family and geographic area, via the pull-down menus.
Each character type has its own window, and as many character types (and
therefore windows) as required may be open at any one time.
The character windows contain the features that are available for use in
the identification. Identification proceeds with the user selecting features
that can be seen on the specimen to be identified.
The features are selected by clicking on the appropriate line in the character
window. At any time, it is possible to remove a selected feature, by again
clicking on it.
A status bar at the bottom of the screen provides information on the current
operation, and on the number of taxa remaining. A species window may be opened
to list the taxa remaining.
