Typematic Keys
All of the data keys and many of the function control keys are typematic. This
means that if the key is held down, it repeats its character or function until it is
released. In the following illustration, the dark keys are the typematic keys.
For an example of a typematic function, press and hold the
J
key for a few
seconds while observing the display screen. Notice that the letter J appears
continuously on the display screen until you release the key.
