THE KEYBOARD
The keyboard of the HP 2624A (figure 1-2) is logically
divided into five major groups of keys.
Alphanumeric Keys-The layout of these keys is similar
to that of a standard typewriter keyboard. These keys are
used for entering alphabetic and numeric data, ASCII con-
trol codes, and the special symbolic and punctuation
characters such as
( ) ?
%
&
and • .
Numeric Pad-The numeric pad is located to the right of
the alphanumeric keys. The layout of this key pad is
similar to that of a standard office calculator. These keys
may be used for high-speed entry of large quantities of
numeric data.
Cursor Control Keys-This group of keys is used for
moving the cursor around on the screen (up, down, left, or
right) and for controlling what portion of display memory
appears on the screen (home up, home down, roll up, roll
down, next page, and previous page).
Edit Control Keys-These keys are used for inserting and
deleting characters and lines in relation to the current
cursor position.
Function Keys-These keys (labeled _
through
m)
perform different functions depending upon which
keystrokes have been performed. At any given time, the
applicable labels for these keys appear across the bottom of
the display screen.
