You can have the same sort of synchronous operation between controls in
different processes running on your computer, or between control s running
in processes on different computers in your network. Lookout networking
makes this possible.

choose how the alarm window is displayed by selecting Alarms»Display
Options. In Figure2-1 the alarm window is set to display at the bottom of

Operator Input and NavigationThere are numerous methods for you to make setpoint adjustments or
switch from one control panel to another. These include mouse, trackball,
touchscreen, and keyboard activated commands.
When the cursor moves over a controllable object, the cursor turns into a
hand, indicating you now have control of the object. Controllable objects
include such things as switches, Pots, and pushbuttons.
When using a keyboard, the arrow keys move the cursor ar ound the screen.
The <Tab> key jumps the cursor from one controllable object to another,
and the <Space> bar acts as the left mouse button, so you can click on a
controllable object without actually using a mouse.
You can also use keyboard function keys to control panels and other
objects, so you can switch between control panels or issue control
commands just by pressing a function key.
Your Lookout administrator can provide you with any special instructions
you need to work with a particular Lookout contro l panel.
Virtual Keypad
When you are in operating mode, you can click on a digital pot control and
bring up a virtual numeric keypad to enter numeric values, either with a
mouse or a touch-sensitive screen.
