1-8: The Mouse

Electric mostly uses the left and right mouse buttons, although there are functions that can use a middle button. On Macintosh systems with only one button, hold the Command key to get the right button functions.

Modifier	Button	Action
	Left Click	Select
SHIFT	Left Click	Invert selection
CTRL	Left Click	Cycle through selected objects
CTRL + SHIFT	Left Click	Cycle through objects to Invert
	Left Double Click	Get Info
	Left Drag	Move selected objects or Select area
CTRL	Left Drag	Move selected objects, constrained
	Right Click	Draw or Connect Wire
CTRL	Right Click	Draw Wire (no connect)
SHIFT	Right Click	Zoom Out
SHIFT	Right Drag	Zoom In
CTRL + SHIFT	Right Drag	Draw Box
	Middle Drag	Pan Screen
SHIFT	Middle Drag	Select area without moving
	Wheel Up/Down	Scroll Up/Down
SHIFT	Wheel Up/Down	Scroll Right/Left
CTRL	Wheel Up/Down	Zoom in/out

By combining special keystrokes with the mouse functions, advanced layout operations can be done:

Switch Wiring Targets Hit Space while holding the Right mouse button to switch between possible wiring targets under the mouse.
Switch Layers Type a number between 1-9 to switch layout layers. You can also use "+" and "-" to move up or down by one layer (when typing "+", it is not necessary to hold the Shift key, so you are really typing "=" on most keyboards). Additionally, if you have a port highlighted that can connect to the new layer, a contact cut will be created at that point and connected to the port.
Abort Type ESCAPE to abort the current operation.
