Hip to be square - Draw perfectly symmetrical shapes

Holding down the “Shift” key while drawing shapes in Office applications makes them resize evenly.  So if you resize a:

• Square it will stay a square and not accidentally become a rectangle.
• Circle it will stay a circle and not accidentally become an oval.

Also try resizing a shape whilst holding down the "Ctrl" key and see what happens...  Feel free to comment below if you try it.
