Xcelsius - Drawing a box around multiple sliders - how?

The following instructions are straight from the Quick Start tutorial in Xcelsius, but I have YET to find out how to draw a box around the five sliders - there is nothing on-line either that seems to answer such a basic question!

4.11. Draw a box around the five slider component开发者_Python百科s to select them all. 4.12. On the Format menu, point to Align, and click Center.

Thanks!

You can click on the canvas and hold the mouse down while you drag the mouse over the sliders. A better method though is to take advantage of the Object Browser window CNTRL+4 where you can select controls by CNTRL + MOUSECLICK on each. It is well worth the small effort required to key in meaningful names for all of the controls/widgets.
