Edit Mode may be entered from the Mode Menu, the Pop-up Menu or by using the Ctrl-E Keyboard Accelerator.
In Edit Mode, the cursor is a delta or four-headed arrow when the mouse button is being held down.
The user can move, duplicate and delete blocks and controls and add new Devices in this mode. You cannot add any wires in this mode; Wire Mode must be used. Wires will be automatically deleted if their source or destination node is deleted through the deletion editing of a block.
