IBM PCjr User Manual

Using the Keyboard
All keys on the keyboard are typematic. This means
that each key repeats as long as you hold the key down.
This is the keyboard that comes with your IBM PCyr.
The positions of the keys are much like those of a
standard typewriter. Most keys on the keyboard have
an uppercase (capital) letter and a lowercase (small)
letter.
Your keyboard has some extra keys that a typewriter
doesn't have.
This is the Enter key.
