Keyboard

The FieldBook has a rugged, sealed, membrane keyboard with tactile response. There are 21
keys that are l/2 inch (1.27 cm) square. Key usage is described below.

On/Off Key:

Toggles the FieldBook on and off.

Function Key (FTN):

Used in custom program-

ming. In an application program, the function key
plus a numeric key can be used to spawn another
activity. For example, <FTN> + <1> can be used
to show a help menu for a data entry field. (See
Section 6, Programming the FieldBook, for details.)

Control Key (CTL):

Enables you to type charac-

ters not included on the keyboard by entering an
ASCII code. The ASCII code is always a three-
digit decimal number. Non-printable ASCII
characters will appear on the display as odd
symbols. A list of ASCII codes can be found at the
end of Section 7, PolyTools Program.

Escape Key (ESC):

Returns you to the MODE?

prompt.

Alphanumeric Keys:

To access the numbers

printed on the bottom of the keys, simply press
the key. To access the letters and symbols printed on the top of the keys, press the shift key
in combination with the alphanumeric key. For example, <SHF> <ABC/7> yields the letter
A. <SHF> <SHF> <ABC/7> yields the letter B.

Shift Key:

Used to access the alphabetic characters and symbols printed on the top of the

keys. Each time the shift key is pressed, a vertical bar is shown on the display. If the shift key
is pressed 3 times in succession, 3 vertical bars are shown on the display.

Arrow Keys:

Used to move the cursor around. Various operations use the arrow keys in

different ways. For example, the right and left arrow keys scroll through the directory when
you are in the File Directory Mode.

Enter Key:

Causes the FieldBook to act on the command or data previously entered.

b (blank space):

The small b (located on the top row of the 0 key) is used to create a blank

space. Press <SHF> <b/0>.
