1-12-2 Screen Buttons
There are many buttons in the shape of keys that can appear during Support
Tool operation. These buttons can be clicked with the mouse to achieve the
same operation as the equivalent keyboard keys. Included are the Enter Key
(carriage return arrow), Escape Key, cursor keys, PgUp Key, PgDn Key,
Space Bar, Shift+Home (clear) Key (one button combining two keys), the
Home (clear) Key, and function keys.
1-12-3 Mouse
A mouse can be connected to the Support Tool and used to input coordinates
to specify display positions for text strings or numerals and to create poly-
lines, circles, and other graphics.
To use a mouse, connect a two-button mouse to the computer’s mouse con-
nector and prepare a level, smooth surface, such as a mouse pad, to operate
it on. The mouse can then be used to move labels, the + cursor, and other
objects on the screen (see below).
Procedures in this manual are generally written for operation from the key-
board. There are, however, often three means to execute an operation, i.e.,
from the keyboard, using on-screen buttons, and using the mouse and cursor
directly. It is generally a matter of preference on which method is used; the
results will be the same.
Left Button The left mouse button can be used in place of the Enter Key to achieve the
following.
•To specify items on menus. Click the mouse once to move the cursor and
then again to execute.
•To click on-screen buttons to replace keyboard key inputs. See page 14 for
details.
•Double-clicking to end polyline input (instead of Shift + Enter).
•Dragging to move objects on screen or draw lines.
•To designate display positions for text or numerals
•To designate display positions for touch switches, lamps, and bar graphs
•To designate center, start, and end points for graphics
Right Button The right mouse button can be clicked in place of pressing the Escape Key to
move backward through processing steps or to cancel an operation.
Caution Although either the mouse or the keyboard can be used for most operations,
some operations have been restricted to only keyboard operation for safety. If
the software does not respond when a mouse button is pressed, use the key-
board instead.
1-12-4 Positioning Operations
Grid display can be set via the Tool Settings, and grid display and snap-to-
grid operation can be set via the Set Environment settings. The grid can be
used either to visually align objects on the display or it can be combined with
snap-to-grid operation to force objects to be positioned exactly on the grid.
Refer to pages 15 and 16 for details.
