Imagine a keyboard that lacks Win key. That's easy to emulate – you just press CtrlEsc. However, on the keyboard I have now, there's no "right mouse" key (or "context menu" key or whatever it might be called – it's usually placed close to AltGr and bears the sign of three horizontal bars or something).
I'm very used to pressing that key and not having it around slows me down (not to mention the annoyance aspect). How can I emulate it on this limited keyboard?
