The contents window in SuperMemo displays the knowledge tree of the current collection
These are the most prominent components of the contents
window:
- Knowledge tree (in the
middle of the window). If you would like to build your own knowledge tree,
read: Creating the structure of a knowledge tree
- Caption (at the top of the window). The
captions shows the full path to the location of the
current collection on the hard disk (or a network drive)
- Toolbars (under the caption):
- Edit toolbar -
buttons used in most frequent operations on the knowledge tree
- Data bar - information about the element that is currently selected in the knowledge tree
- Title tab - edit area for editing element's
title
- Editing buttons (at the bottom of the window):
- View - view the currently selected element
in the element window
- Learn - make
repetitions for the selected branch and memorize pending elements belonging to the branch
- Add - add a new element as a child of the currently selected element (a child is an element that
is one level down in the knowledge tree)
- Sibling - add a new element as a sibling of the currently selected element (a sibling is an
element is is on the same level in the knowledge tree)
- Insert - insert a new element in the place
of the currently selected element (the current element moves one position down)
- Delete - delete the currently selected
element and all its children (if any)
- Accept - accept the choice of the currently
selected element. This button is active only if another option in SuperMemo requires
selecting an element. In such a case, the contents window is opened and you can point to
the element of interest and click Accept). For example, choosing Hyperlink
on the component's pop-up menu will open the contents window
and ask for selecting an element to link to

In the figure above, red stop icons denote
dismissed elements (i.e. elements that do not participate in learning), while L-plate
icons indicate elements that take part in the learning process. L-plate icons are light
blue if the element is pending (i.e. waiting for
memorization) and dark blue if the element is memorized
(i.e. included in the repetition schedule)
The plus sign to the left of the element
indicates that the element has children. You can see the children when you click the plus
sign. The minus sign to the left of the element indicates that the element with children
can be collapsed. When you click the minus sign, all children will disappear from view and
the minus sign will be replaced with a plus sign
