Components of the Sym application
The three main components of the Sym application are the content, the tools used to edit and manage the content and the libraries that provide the objects and functionality that are used to create and edit expressions.
- Content
  Content windows include Document Modules, Object Modules and Unit Test Modules. With the exception of the Properties windows which are attached to modules, all of the windows in the Sym application can be dragged and docked in a variety of locations to provide a way to customize the layout of the main application window.
- Tools
  In addition to the content of the application there are several tools available to assist you in creating and managing the content of a document, like the Document Explorer, Object Browser and Unit Test Runner.
- Libraries
  There are a number of libraries that are available online that can be used with Sym documents.
- Dialogs
  - The Rendering Editor
    Renderings control how each object is displayed in a document. Renderings are created and edited using the Rendering Editor and are attached to object definitions in Object Modules. An object definition can contain zero, one or more renderings. If no rendering is assigned to an object definition, a default rendering is used to display the object.
  - The Options Dialog
    The Options dialog is used for settings that are independent of the document that is currently loaded. The settings include the document location, the export location and whether or not type errors are fixed automatically.
  - The Document Options Dialog
    The Document Options dialog is used for settings that are part of each document. The settings include the Copy Exporter and the Notation. The Document Options dialog is opened by selecting Edit > Document options... from the main menu.
