To select items in a tree view or hierarchy view, use the following commands in the right-click menu:

• Select This / Deselect This: These commands work as a "toggle" to alternately select and de-select the node.
• Select Branches / Deselect Branches: These commands work as a "toggle" to alternately select and de-select all sub-nodes that are beneath the node. (Note that the "parent" node is not selected; you will need to use the Select This command separately to select it.)
• Select All / Deselect All: These commands work as a "toggle" to alternately select and de-select all nodes in the tree view regardless of whether they are visible.
• Select Visible Items / Deselect Visible Items: These commands work as a "toggle" to alternately select and de-select only the nodes that are visible in the tree view.
