Sometimes we need to add a few symbols to a document and spend too much time looking for a picture, when a key code sequence will work just as well, if you are using Windows. These use the numeric keypad on the keyboard, not the numbers across the top. For instance, if you need to put a copyright symbol next to a company name, push the num lock key to use the number pad, then hold down the ALT key and type 0169, release and you see © , Alt 0153 works for trademark ™, Alt 0174 works for the trademark registered symbol ®. (Some keyboards require holding the shift and alt keys while typing numbers or the FN key and alt). The symbols show up when you release the ALT key.
To try them yourself, go through the numbers from 1
thru 127 then 0128 thru 0255, such as ALT 1 ☺, ALT 2 ☻, ALT 3 ♥,
ALT 0128 €, ALT 0165 ¥, ALT 0189 ½, etc., to find some
happy surprises. Incidentally, these work in Word documents
as well as email, etc,. Facebook has its own set. You can also
use Windows. Type in character map in the search box and it
will show the full list.
