When opening a navigation tree you can either open the navigation tree you are currently working with or a navigation tree that you have access to, but are not currently working with.
For more information on how to:
open the navigation tree you are currently working with, see the section "Open the navigation tree you are currently working with"
open a navigation tree that you have access to, but are not currently working with, see the section "Open a navigation tree that you have access to, but are not currently working with".
Note that if you only have access to one navigation tree you can disregard the information in the section "Open a navigation tree that you have access to, but are not currently working with".
