In VMware Fusion, you can use shortcuts to operate a single-button mouse as a two- or three-button mouse.

The defaults are Control + primary button to mimic the secondary mouse button (right-click) and Command key + primary button to mimic a third button.

You can change the shortcut.

1

Select VMware Fusion > Preferences and click Keyboard & Mouse.

2

Click Mouse Shortcuts to go to the mouse shortcuts pane.

3

Double-click the mouse shortcut and hold down the keys for the new shortcut.

To restore the defaults, click Restore Defaults.
