Shift + Option + 8 is a keyboard shortcut for typing a degree symbol on Mac. With this shortcut, your field will display a degree sign like 95°.
Two other shortcuts add a degree-like sign to the text but are actually used for different things.
Option + K: This one places a tiny ring inside - 95
To type the Ring over a diacritical mark, use this method.
Alternative 0 (ZERO): A sign-writing option: 95o
It is the written form of the masculine ordinal indicator.
