But Ø is a Capital O with stroke (Unicode 00D8), not a struck-through 0. Kilroy's ø is the small o with stroke (Unicode 00F8). There is no struck-through 0 in Arial. Kilroy's EQ field is about as close as you'll get with a true 0, though you might need to reduce the point size of the / to centre it on the 0.

So far, no luck. And thank you all so much for your help! I have described myself as a "Digital Dinosaur" and need all the help I can get.

The Ctrl F9, equation, Shft F9 worked to produce a pretty good looking symbol when placed in a new word doc, but when I copy paste into the auto correct it shows up as 0\. the symbol did not show up already in the replace with box as Kilroy suggested.

I tried to enter the equation by copy paste direct into the replace with box, it would not "take".

Is there possibly a way to place the symbol resulting from the equation into the symbols library and then to the autocorrect? As a "custom" symbol?
