Character Map (£$¥¢©)
If you need to type special characters which you can't find on the keyboard, such as £, $, ¥, ©, ½, etc., then press Start and type Character Map. Then hit enter, or select character map from the list to open the Character Map.
From there you can find the special character you are looking for, choose a font if necessary, learn the keystroke to type that character, or simply double-click the character to select it, then copy using the copy button and paste the character into your document or app you are using.
(Copy and Paste can also be achieved by pressing Cntrl + C and Cntrl + V.)
