Need help to place degree marks after number instead of writing out degree.
For the default keyboard shortcut, press Ctrl+@ (that is,
Ctrl+Shift+2), release it and press the spacebar.
Or hold down the Alt key while you type the code 0176 on the numeric
keypad with NumLock turned on.
If you can't remember that, then use Insert > Symbol, set the Font box
to "(normal text)", and look for the degree character 21 boxes after
the 'z'.
In any of these ways, you should get the ° character.
