<P> Standard alphanumeric keyboards have keys that are on three - quarter inch centers ( 0.750 inches , 19.05 mm ) , and have a key travel of at least 0.150 inches ( 3.81 mm ) . Desktop computer keyboards , such as the 101 - key US traditional keyboards or the 104 - key Windows keyboards , include alphabetic characters , punctuation symbols , numbers and a variety of function keys . The internationally common 102 / 104 key keyboards have a smaller left shift key and an additional key with some more symbols between that and the letter to its right ( usually Z or Y ) . Also the enter key is usually shaped differently . Computer keyboards are similar to electric - typewriter keyboards but contain additional keys , such as the command or Windows keys . There is no standard computer keyboard , although many manufacturers imitate the keyboard of PCs . There are actually three different PC keyboards : the original PC keyboard with 84 keys , the AT keyboard also with 84 keys and the enhanced keyboard with 101 keys . The three differ somewhat in the placement of function keys , the control keys , the return key , and the shift key . </P>
