Using Your Mouse with IDL
IDL supports the use of mice with up to three buttons. Because some systems use mice with one or two buttons, IDL provides mechanisms for simulating a three-button mouse.
Using a Two-Button Mouse
Some mice used with Microsoft Windows systems have only two buttons. See your system documentation for information on emulating a middle-button press.
Using a Macintosh (One-Button) Mouse
Some mice used with Macintosh systems have only one button. The X Window System software provided with MacOS X provides multi-button mouse emulation, allowing you to configure the system to generate middle- and right-button press events. See your MacOS X system documentation for details.
