You can use buttons on the Hierarchy window toolbar or the View menu,
or pop up on an empty space in the window to access the following
options. For more information about the Hierarchy window see the

Redraw—Rearranges nodes after successive operations on hierarchy nodes
if you need to minimize line crossings and maximize symmetric aesthetics.
If a focus node exists, you then scroll through the window so that the first
root that shows subVIs is visible.

You can drag a VI or subVI node to the block diagram or copy it to the
clipboard by clicking on the node. <Shift>-click on a VI or subVIs node to
select multiple objects for copying to other block diagrams or front panels.

Double-clicking on a VI or subVI node opens the front panel of that node.
Any VIs that contain subVIs have an arrow button next to the VI that you
can use to show or hide subVIs. Clicking on the red arrow button or
double-clicking on the VI itself displays the subVIs in that VI. A black
arrow button on a VI node means that all subVIs are displayed. You also
