Context Menu on Middle Mouse Button

I use a mouse with scroll wheel and all the bells and whistles on Rhino for Mac for a more seamless experience between mac and win. Also, I like having the RMB to repeat the last command and the middle mouse button (MMB) with the context menu, which on Windows gives the most recent commands. The closest way of emulating this behavior on Mac is to run a macro on the MMB with _PopupPopular. But it is not the same as Recent Commands context menu.
So my question: is there a command to call the context menu that I can assign as a macro to the MMB?

Thanks
