Middle Mouse Button Click via Hotkey Modifier in OSX?
If you can hold the control key and click to get a right click, is there another modifier key you can hold to get a middle mouse button click. I don't think there is, so is there a way to create one?
One option would be to use KeyRemap4MacBook:
You can add custom settings in private.xml. See the source for the key and button constants and predefined settings.
Command key+click will normally act as a middle mouse click. For example, Command+click a link in a web browser like Safari will act like a middle mouse click.
