This sub-menu contains options that control the behavior of the Project Explorer.
These options expand and collapse the Table of Contents and Topic Files display in the Project Explorer.
This allows you to filter the Table of Contents display on the basis of your build options/include options. It will only have any effect if you have actually assigned build options to your topics. See Conditions and Customized Output for more details.
Note that this function only filters topics in the TOC, it does not filter content in your topics tagged with build options using the Conditional Text tool.
This protects your TOC against accidental changes with the mouse. This can be useful when you are just editing your project and are no longer making any changes to the TOC.
Open the current topic in a new tab in the Help+Manual editor.
