To play a subject: By default, the subject interface consists of an Outline pane on the left and the content display area on the right. The Outline pane displays the status of sections in a hierarchical outline. Clicking a plus symbol (+) displays subordinate levels and clicking a minus symbol (-) hides subordinate levels. Subject sections containing other sections are represented by book icons. Sections containing content files only are represented by page icons.
There are two modes available for running a subject: Sequenced and Explorer. How you navigate the outline depends upon the mode. In Explorer mode, which is the default, you can choose subject sections from the outline at random. Therefore, you are not limited to taking a subject in a predefined order. In Sequenced mode, you move sequentially through the outline, working through each section from beginning to end. As you complete subject sections, the tracking status icon next to the section indicates completion. When all subsections within a section are complete, the tracking status icon next to the main section shows completion.
You can resize the Outline pane and content display area by clicking the mouse pointer on the border between them, and then dragging the border to resize it. You can begin dragging when the mouse pointer changes into a double-headed arrow.
As you move through the subject, content will display on the main screen. The nature of the content may vary. There may be interactive steps within the content that require you to click to a next step. Audio and animated presentations may also be included as part of the subject content.
