Hi, I'm trying to customise the Logitech S530 mouse for tabbed browsing in firefox. I want the middle button (i.e. the scroll wheel), to open a new tab in Firefox. Now the way I'd usually do this is by holding the Apple key and then left clicking. [Alternatively I could use the right click menu, I know]. However, in the Logitech Control Center (in System Preferences), I don't seem to be able to use a key modifier with a mouse click. I can use a key modifier with a keyboard button - "Apple-N" for example - but not "Apple-L.H.Click". Does anyone know a solution?
