Left Click

  • Selects a component and populates the properties

  • (+ Shift) an unselected component appends a component to the selection list

  • (+ Shift) a selected component removes the selected component from the selection list

  • Starts a link if mouse over a pin

  • Ends a link if drawing a link and over a pin

  • If drawing a link and over a wire places a junction and connects the link to the junction

Double Left Click

  • Quits drawing a link if drawing a link

Right Click

  • If over a component Shows Context Menu

  • Quits drawing a link if drawing a link

Right Mouse Down

  • Starts Pan Mode if not over a component

  • Starts draggin the selected components if over one of the components in group

Right Mouse Up

  • If dragging selected components drops them into new location

  • If panning stops panning

Mouse Scroll Button

  • Scroll Up to Zoom-out. Zoom will center to the location of the mouse.

  • Scroll Down to Zoom-In. Zoom will center to the location of the mouse.
