You can use a mouse, digitizing tablet cursor, or similar pointing device to enter graphical input.
Physical buttons on the input device are mapped to "logical" buttons, which send different types of graphical input to OpenUtilities Substation . For example, the left mouse button is mapped to a logical button called the Data button, which sends a type of input called a data point to OpenUtilities Substation when pressed.
The Button Mappings dialog lists the current button mappings for your input device. It shows you how the "logical" buttons are matched to the physical buttons. In this dialog you can remap these buttons to meet your needs. For example, you may want to change the buttons if you are left handed or if you use a laptop with a touchpad.
Using the Button Assignments dialog, it is possible to assign any key-in and to add key combinations to logical buttons, thus creating additional button assignments. Many button-key combinations are assigned by default, but even these assignments are customizable.
