It’s getting cold and I’ve started marking daily temperature on my running log. Which made me think, does everybody know how to type the degree (º) sign?
On both British and US English QWERTY keyboards, press the Option (ALT) key and type zero in the top row of the keyboard (not on the zero in the numerical section of an extended keyboard.) The large zero will turn into a tiny degree sign shifted upwards.
Then you may add C for Celsius or centigrade or F for Fahrenheit: -1ºC or +30ºF.
Wikipedia has an article on various temperature measurement systems here.
If you are looking for weather clip art symbols, there is a selection of them in the Special Characters palette. Under Edit, got to Special Characters, and when the palette opens, look in the Symbols > Miscellaneous folder. A selection of snowflakes is also there.
Click on the symbol and drag it to your document.
