The code will stick in your memory if you use it often enough- 'Alt-0176'.
If you're running Windows, hit the 'Start Button'-'All Programs'-'Accessories'-'System Tools'-'Character Map', and
voila, there are all of the special characters you will ever need. 'Alt-0169' is another that I have at my command.
I have to look up all others.
Copy and Paste will also work if you have an example at hand.
