The System - Mouse Wheel Configuration page of the Preferences dialog
The System - Mouse Wheel Configuration page of the Preferences dialog is used to configure how the mouse wheel functions. You can configure the mouse wheel functioning for all editors, or specifically for PCB and/or schematic documents.
The dialog is accessed by clicking Mouse Wheel Configuration under the System folder in the main Preferences dialog (DXP » Preferences).
Mouse Wheel Configuration
Action - a list of actions for which the mouse wheel can be configured. These configurations are for a mouse that has a wheel between two mouse buttons. As noted in the grid, Launch Board Insight, Change Layer, Zoom Insight Lens, and Insight Lens Auto Zoom are configurations that affect the mouse wheel only in the PCB Editor; Change Channel affects the mouse wheel only in the schematic.
Action items that do not specify a specific editor will configure mouse wheel operations in all editors, including Draftsman.
Button Configuration - use these options to configure any keyboard button combination (Ctrl and/or Shift and/or Alt) that is required to be used along with the mouse wheel function (as listed in the grid) to perform that action.
