<Chapter 10: Keys with Special Functions>
This chapter describes the single keystroke commands: the function
keys, the numerical key pad keys, and certain control keys used when
editing text strings.
<Section 10.1: Function Keys>
<Section 10.1.1: F1: Help>
Pressing F1 at any time activates the HELP system, which gives you
on-line access to the entire text of the ORCHIS manual. The portion of the
manual which appears is indexed to the current menu and the current
operation. The HELP system is fully described in Chapter <[11]>.
<Section 10.1.2: F2: Complete screen redisplay>
If you press F2 at any time, the entire ORCHIS screen display will be
erased and redrawn.
<Section 10.1.3: F3: Total Mode Toggle>
This command is available when you are displaying a chart. It toggles
between two modes governing the display in the chart window: TOTAL (the
chart image is stretched or shrunk to exactly fill the window) and PARTIAL
(a portion of the chart is displayed according to position and stretch
information associated with the window). F3 has no effect if you are
displaying a form.
<Section 10.1.4: F4: Center Window at Cursor>
This command is available when you are displaying a chart. It first
toggles out of TOTAL display if necessary, and then moves the view in the
chart window so that the new center of the window is the point that was
occupied by the cursor at the moment the F4 command was invoked.
F3 and F4 can be used in combination to navigate rapidly about the
chart. First press F3 to toggle into TOTAL display. Point with the cursor
at the box in the chart you want to examine, and then press F4. ORCHIS
will toggle out of TOTAL mode, and display the selected box at the center
of the chart window.
F4 has no effect if you are displaying a form.
<Section 10.1.5: F10: Super-Escape>
Use the super-escape key, F10, to return in a single step from the
current menu to the ORCHIS top menu. This command is equivalent to
pressing the escape key again and again until you reach the top level
menu.
<Section 10.2: NumPad Key Commands>
The keys of the numerical key pad are used to move the cursor, to
shift the view when a chart is displayed, and to move to neighboring boxes
when forms are displayed. These keys have different functions when in the
HELP system. See Chapter <[11]> for more information.
<Section 10.2.1: Cursor Motion Keys>
Pressing an arrow key in the numerical keypad moves the cursor a
single step in the direction of the arrow. See <[FIG09]>.
<Section 10.2.2: Shift Arrow Keys>
In chart view, holding down a shift key while pressing an arrow key
moves the chart display view by one half of the window size in the
direction of the arrow. Thus pressing shift-right moves the chart window
to the right (picture elements appear to move to the left inside the
window).
In form view, the shift-arrow keys move from the current box to one
of its neighbors. Shift-up moves to the parent box of the current box.
Shift-left and shift-right move to its sisters. Shift-down moves to the
first daughter of the current box.
<Section 10.2.3: Shift Corner Keys>
In chart view, holding down a shift key while pressing the Home key
causes the chart display window to be re-positioned at the extreme upper
left corner of the chart. Similarly, shift-PgUp moves the chart window to
the upper right corner of the chart. Shift-PgDn and Shift-End move to the
lower right and lower left corners respectively. See <[FIG12]>. These keys
have no effect in form view.
<Section 10.2.4: Grey Plus Key>
This key enables and disables automatic cursor motion. Press the
Grey-plus key followed by a cursor motion arrow key to start the cursor
moving at a constant rate in the direction indicated by the arrow. Press
the same cursor motion key again to accelerate the motion. Press a
different cursor motion key to change the direction. Press the Grey-plus
key again to stop the motion.
<Section 10.3: Text Editing Control Keys>
When you are editing a text string, a number of control key commands
become available, and the command menu is replaced by a list of these. The
new commands are:
Ctrl-F: move text cursor forward 1 character
Ctrl-B: move text cursor back 1 character
Ctrl-A: move text cursor to start of line
Ctrl-E: move text cursor to end of line
Ctrl-K: delete from cursor to end of line
