The Series 3300 Keyboard

The keyboard is the primary means for entering data and issuing commands on
the Series 3300. The standard 56-key and 35-key keyboards are illustrated in
Figures 3-6 and 3-7, respectively.
The keys on the keyboard are distinguished as modifier keys and character keys.
Because the 3300 keyboards have fewer keys than PC keyboards, each character
key can produce more than the usual one or two characters. The four modifier
keys, Shift, CapsLock (Alpha on the 35-key keyboard), Ctrl and Func, used
individually or in combinations, determine which character or special function is
produced by the character keys.

Using the Keyboard

Except for boot operations, the Series 3300 expects keys to be pressed one at a
time. Depending on the configuration (whether ERR3000 is loaded), the system
may indicate a Double Key error if two or more keys are pressed simultaneously.
Accordingly, all key sequences must be entered by pressing and releasing one key
before pressing the next.
The keyboard also has an optionally configurable auto-repeat function. If set,
when the operator presses a character key and holds it, the character is repeated
as long as the key is held. If the key is pressed immediately following a modifier
keys, the modifier sequence affects only the first occurrence of the character key.
For example, Shift followed by pressing and holding A generates: Aaaaaa...
