Keying in Special Characters
Although most of the 256 characters that can be displayed on the
HP 48 are available on the Alpha keyboard, it is easy to forget the
particular sequence of keystrokes needed for the less-frequently used
characters.
The CHARS application is designed to avoid this problem by enabling
you to select characters directly from the display and insert them at
the cursor point. CHARS displays the HP 48’s characters 64 at a
time, along with the number of each character and the keystroke used
to type it in from the alpha keyboard.
