Function Keys
There are four function keys,
<F1>
through
<F4>
, at the top of the
keypad. Alpha mode changes these keys to
<F5>
through
<F8>
. Actions
assigned to the function keys are determined by the active program.
Action Keys
There are four action keys:
<I/O>
,
<Alpha>
,
<BKSP>
, and
<ENTER>
.
<I/O>:
Press this key to turn the portable on and off. When turned on,
the portable beeps and returns to its previous location when it last shut
off. The portable does not beep when the
<I/O>
key is pressed to turn the
unit off. The
<Alpha>
key has no effect on the
<I/O>
key.
<Alpha>:
Press the
<Alpha>
key to toggle between normal and alpha
modes. In normal mode, a press of a key either inserts the nonletter
character printed on or above the key or performs an action (for
example, clearing the entry or scrolling through the display). In alpha
mode, a press of a key inserts the letter printed on it.
The following example uses two keys to illustrate the difference between
alpha mode and normal mode:
