Focus on a sub-structure

Tree structures can grow both large and wide. With the focus icon , you can focus on a particular sub-structure in the tree. Where the focus icon is visible (shown at the right side of a tree object), you may click the icon to show the isolated sub-structure on the upper-left side of the browser screen, while hiding the rest of the tree. Clicking the focus icon at the top of tree will restore the original tree structure.

Note: When hovering over the focus icon with your mouse, a tooltip will show the meaning of the icon.
