Alphabet Keys

            The keys on which A–Z letters are written are called alphabet keys. Alphabet keys
            are 26 in number. They are used to type words and sentences. The alphabet keys are
            used to type both capital and small letters.
















            Number Keys

            Number keys are marked with the digits 1, 2, ..., 9 and 0 (zero) on them. These are
            10 in number. Number keys help you to type numbers. There are two sets of these
            keys on a keyboard.







            Special Keys


            There are some keys that have a special role. Let us discuss some of them.

            Spacebar Key
            Spacebar  is the  longest  key  at  the  bottom of

            the keyboard. It is used to give a blank space
            between two letters, numbers, symbols and words.




                           Spacebar is the only key on the keyboard on which nothing is
                           written.



                             Enter Key

                             We use the Enter key to move to the next line. The Enter key is also
                             called the Return key. There are two Enter keys on a keyboard.

            Backspace Key

            We use the Backspace key to erase what we have typed.
