The Help browser is called up via:
- Help buttons,
- '?' help buttons,
- context menu Help actions,
- Tools->Help Browser,
- Help->Help, and
- pressing the F1 key.
The left column contains type (object class) names -- click on them to obtain information about that object type. Use the search field to find what you're interested in.
The right column contains the help information, with tabs for each new item that is clicked. Just delete tabs (using the x on the tab itself) if it is no longer relevant.
For object type information ("reference information"), which is automatically extracted from the source code, you will see an embedded frame from the wiki for that type name as well, followed by all the reference information. This information is mostly useful for Programs but also can be useful for other uses.
