I wanted to reply to a FB post with a temperature, but also wanted to include the "degrees" symbol. I noticed that it was not to be found anywhere on my keyboard. A quick google search gave me this, which worked:
Hold Alt then press 0 1 7 6 in order, then release Alt to get " ° ".
Not too difficult and fairly easy to remember.
I like to post new things that I learn so I can refer to my blog at a later time for reference.
