You can use a mouse, digitizing puck, or stylus as your pointing device, and it may have more than two buttons.
You can control this program with a pointing device such as a mouse, digitizing puck, or stylus. A pointing device may have a number of buttons. The first 10 buttons are automatically assigned by the program, except button 1 the pick button. The behaviour of the buttons can be changed by modifying the main customization (CUIx) file. You can also change how mouse buttons function through the operating system.
Pointing Device Buttons
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
The contextual behavior of the right-click operation can be modified using the SHORTCUTMENU system variable. Additional buttons on a pointing device can be customized in the main customization (CUIx) file.
Mouse Wheel and Middle Button
Many mice provide left and right buttons in addition to a wheel located between the two buttons. You can use the wheel to pan and zoom in a drawing without using any commands.
By default, the zoom factor is set to 60 percent; each increment in the wheel rotation changes the zoom level by 60 percent. The ZOOMFACTOR system variable controls the incremental change; higher the number, the larger the change.
The following table lists the wheel mouse actions supported in this program.
