The following lessons provide a step-by-step introduction covering the most important features of CaseTalk. Every lesson is divided into several exercises. Each lesson starts with a brief summary of the topics covered. The average lesson takes about 30 minutes to complete.

This lesson contains several remarks you should know before you can start.

Installation

Before you start with the lessons you need to install CaseTalk. In the lessons we refer to the installation folder for CaseTalk as ...\CaseTalk.

Configuration File

If CaseTalk was installed on your computer you will find settings and configuration files in your roaming profile folder (..\Users\<username>\AppData\Roaming\Casetalk<Version>). By removing these files CaseTalk will be restored to the default options.

Displayed expressions

Because the space character can be be part of the predicate of an expression CaseTalk will, in most cases, display the space character as a little dot.

The MS Windows interface

Rollup's A rollup window is a small window 'floating' above all other windows.

Popup-menu's A popup-menu is a menu which appears when you point to an object (using your mouse cursor) and click the right mouse button.

Dragbox A dragbox is used to select multiple objects at the same time. Place the mouse cursor on an empty area of the diagram, press the left mouse button and move the mouse cursor. While you are moving the mouse cursor (still pressing the left button) a rectangle with a dotted line appears. All objects within this rectangle will be selected as soon as you release the left mouse button.

Drag-and-drop Select the object with the mouse cursor, keep the left mouse button pressed, while you move the mouse. Release the left mouse button if the object is at the correct position.

Double click Click an object twice within a short time interval.
