The first 10 pointing device buttons are automatically assigned; you can reassign all except button 1, the pick button.
On a two-button mouse, the left button is the pick button used to
- Specify locations
- Select objects for editing
- Choose menu options and dialog box buttons and fields
The operation of the right button on a mouse depends on context; it can be used to
- End a command in progress
- Display a shortcut menu
- Display the Object Snap menu
- Display the Toolbars dialog box
Right-click operation can be modified in the Options dialog box (OPTIONS). The operation of additional buttons on a pointing device is defined in the menu file.
The wheel mouse has a small wheel between the buttons. The left and right buttons behave the same as they do on a standard mouse. You can rotate the wheel by discrete values. You can use the wheel to zoom and pan in your drawing without using any commands.
By default, the zoom factor is set to 10 percent; each increment in the wheel rotation changes the zoom level by 10 percent. The ZOOMFACTOR system variable controls the incremental change, whether forward or backward. The higher the number, the larger the change.
The following table lists the wheel mouse actions supported in this program.
