YPEMATIC
Most keyboards have an internal seven-bit “typematic” setting, which governs the
way the keyboard responds when you hold a key down to force it to repeat. The five
“low” bits of this setting represent the rate at which the key repeats; the two “high”
bits represent the delay after you begin holding down the key before it begins to
repeat. Sometimes a keyboard’s typematic setting isn’t suitable for a given operator
or for a given application. To change the typematic setting of your station’s shared
keyboard, issue the Set Keyboard Typematic command: Press and release the left
Control key, type [A] followed by the desired “typematic value,” and press
[ENTER]. The “typematic value” is the decimal equivalent of the binary seven-bit
typematic setting: While the typematic setting = delay bits + rate bits, the typematic
value = decimal delay value + decimal rate value (see Table 4-4 below and Table 4-5
on the next page). For example, to set your shared keyboard to register a key
16 times per second after the key has been held down for half a second (typematic
value = 7 + 32 = 39), type [Ctrl] [A] [3] [9] [ENTER]. Enter the Keep Settings
command after you enter this command.
