Fixed loads can be set on circuits in the Circuiting dialog box using just the keyboard. Not having to use the mouse can speed up the data entry process.
Use the Circuiting command to open the circuiting dialog box.
Ribbon: DM Electrical->Circuiting and Homeruns-> 
Circuiting
Pulldown Menu: DM Electrical->Circuiting and Homeruns->Circuiting
Use your mouse to select the first circuit you want to change a load on. Your mouse will be optional from this point forward.
Type ALT+S to press the Set Circuit Information button. The Set Circuit Information dialog box will appear, shown below:
The cursor will be located in the Circuit Description Prefix field. Enter a description for the circuit.
Next to each field where you can enter a fixed load is a letter. Type ALT and the corresponding letter to move the cursor to the load you want to enter. Loads are grouped together in sets of three. Type ALT+Letter to cycle through the load types that share a letter.
For example, the first three load types are Lighting, Largest Motor, and Other Motors. All three have an A next to the fixed load field. Type ALT+A to move to the Lighting field. Type ALT+A again to move to the Largest Motor field. Type ALT+A a third time to move to the Other Motors field. Type ALT+A once more to move back to the Lighting field.
Type , (comma) and . (period) to move to the previous and next circuit without closing the dialog box.
Press ENTER when you are finished to save your changes and close the dialog box.
If you make a mistake, press ESC to close the dialog box without saving.
When you return to the Circuiting dialog box, the circuit list will have focus. Press the Up Arrow or Down Arrow to move to the next circuit. Press Tab to move from the odd circuits to the even circuits. Press SHIFT+Tab to move from the even circuits to the odd circuits.
Select the next circuit you want to modify and press ALT+S to open the Set Circuit Information dialog box.
Repeat this process until you are finished. You can then use your mouse to select another Distribution Equipment from the list at the top of the dialog box to continue changing circuit loads.
