The typewriter-like keyboard functions in either uppershift or lowershift.
Type the upper symbol (for the keys with two symbols) when the keyboard is in uppershift. Type the lower symbol (for the keys with two symbols) when the keyboard is in lowershift. Type uppercase characters for alphabetic keys (which have only one symbol) when the keyboard is in uppershift. Type uppercase alphabetic characters when the keyboard is in lowershift, unless the Check Lowercase (CHECK(LC)) keyword is specified. If the CHECK(LC) keyword is specified, and you place (or leave) the keyboard in lowershift, you can type lowercase a through z characters.
The following figure shows the typewriter-like keyboard.
