keyboard trick
"To get a ° - on a desktop keyboard, hold down
the ALT key and hit the numbers 0176 on the number keypad.
No idea why it only works for me on a number pad, not on the top row nor on a laptop.
Ask in the Computer forum?"
The key-codes (as the operating system senses them) are different for
the numeric block keys and top row keys on an ordinary keyboard. The feature
works only for the key codes of the numeric keypad. Notebook's top row keys are
equivalent to top row keys o an ordinary keyboard - that's the point why it don't work.
