sealed rubber You may have to watch your parsing here; I'm not sure of my ground, but I have a suspicion that 'sealed rubber' goes together (so 'caoutchouc étanche' rather then 'clavier étanche'), just as 'plastic emissive' goes together — I think it refers to the type of technology used for the keys.

However, it is just possible that there is a comma missing from the original sentence; imagine it was in fact meant to read: "Optional: Backlit, sealed rubber or plastic, emissive"...

Are these options available on the same keyboard, or rather, an entire optional type of keyboard that may be supplied?
