Operating the PDT 6800 Series
Figure 5-2. 46-Key Keyboard
Using the Keyboard
Except during boot operations, the terminal expects the operator to press keys one at a time.
If the terminal has been programmed for it (ERR3000 is loaded), and if two or more keys are
pressed simultaneously, the terminal indicates a Double-Key.
The keyboard also has an optionally configurable auto-repeat function. If the application
allows, a character repeats as long as the key is held down. If the key is pressed immediately
following a modifier key, the modifier sequence affects only the first occurrence of the
character key.
Modifier Keys
The Shift, Alpha, Function, and Control keys are modifier keys. When pressed individually
or in certain combinations, these keys change the keyboard state and possibly the character
produced by the character key subsequently pressed. Refer to Table 5-1 for a list of the
terminal’s special keys.
For example, pressing <FUNC> followed by <CTRL> produces Alt characters, with the same
effect as pressing the Alt key on a PC.
