What is rubberbanding and how do I use it?


Rubberbanding is a schematic mode that can be enabled or disabled from the Options-Circuit section of the Preferences
dialog box available under the Option menu. When it is enabled and you drag wires or components, they stay
connected to their original nodes. If it is disabled, dragging can, and usually does, disconnect components
and wires from other nodes.
Rubberbanding is extremely useful in "dressing up" a poorly drawn schematic. You can improve part
spacing, loosen up densely packed circuit areas, and generally improve the readability of your schematic
with rubberbanding. Just drag select the circuit fragment that you want to move, then left-click
on it and drag it to a new position.
When using rubberbanding to edit a circuit, you often arrive at a point where you need to temporarily
disable or re-enable the rubberbanding feature. Pressing SHIFT + CTRL + R can be used to
rapidly toggle the rubberbanding mode off and on.
