You may encounter situations where the cursor has entered a program-defined 
numeric input field (thereby placing the keyboard in Numeric Mode) and you 
must enter one or more alphabetic characters.  The Alpha ( 
(). 
) shift key 
is 
provided to enable 
you 
to 
enter alphabetic characters into a program-defined 
numeric input field.  To enter alphabetic characters when the keyboard 
is 
in 
Numeric Mode, press and hold the Alpha shift key, and then key in the desired 
alphabetic character or characters. 
After reading this section, 
turn

"Similar Keys 
on 
Typewriter and Data 
Entry Keyboards," in this chapter, for descriptions 
of 
other keys on the 
Data Entry keyboard. 
Typamatic (Repeat-Action) Keys 
Most 
of 
the keys are called typamatic keys.  This means 
that 
they have the 
ability 
to 
repeat their characters or their function automatically if held down. 
The keys that have this capability are  shown in  Figure 3-14.  The discussion 
of 
each key also  mentions the typamatic capability if it applies.
