Rule
The four cursor movement keys move the cursor in the direction indicated by the
arrow without affecting the existing data.
When the cursor reaches the edge of the display screen by pressing a cursor
movement key, the cursor goes off the edge and reappears at the opposite edge
of the display screen. (This cursor movement is called "wrap").
The roll function is used to move data on the display screen up or down. The roll
function is activated by pressing and holding a Shift key, then by pressing the
desired Roll key.
Pressing the Roll up key causes the next page (data below the current display
screen) to replace the current data. Pressing the Roll down key causes the
previous page (data above the current display screen) to replace the current
data.
The home function operates in two ways. Pressing and holding the Alt key then
pressing the Home key moves the cursor to the home position (usually the first
input position of the first input field).
When the display screen is unformatted, pressing and holding the Alt key then
pressing this key moves the cursor to the first input position on line one.
The rule function (activated by pressing the Rule key) enables or disables the
indication of the ruler (one of the three selectable ruler styles; vertical,
horizontal, and cross-hair) that can be specified by the Rule Style (Cmd2) key in
setup mode. See Chapter 3, "Operations Using the 122-key Typewriter
Keyboard" for more information about the ruler style function.
