The largest block of keys on the keyboard is the alphanumeric keyboard with all
the keys for the letters of the alphabet, numerals and special characters. The
characters are arranged in basically the same way as on a normal typewriter.
However, there are a number of special keys which have special functions for
the PG 720.
The special keys in the alphanumeric keyboard have the following functions:
