Hi, All.
I've made a shape to magnify text in the selected shape. Mag Text is stays at the upper left corner of the Visio drawing window. If you move the window or zoom the window, Mag Text moves and changes its size. But if you click the shape or page, Mag Text returns to the position and the size. If the shape is written with multiple fonts and sizes, Mag Text reflects the them. More details are here.

Cool stuff (as usual), June! Thanks for submitting this.
On a magnification-related note, some of you may be interested in this odd download:

Yes, your shape is like a miracle and inspired me to make this shape.
