Collapse - Collapses the whole tree revealing only the available programs.
Expand One Level - Expands the tree an additional level revealing the modules within each program.
Expand All - Expands the whole tree revealing all programs, modules, and functions.
Make your changes (disable or enable as many programs, modules or functions as you need).
