I'm wondering about the usage of slash/stroke as a way of separating alternatives (perhaps it, in this sense, could be called a abbreviation of "or"?). If the alternatives are similar, but the second one is longer, then how would I write this as short as possible, with the smallest possible risk for confusion? Let me give you an example:
I have a card reader where you can insert a Memory Stick or a Memory Stick Pro. If I label the card reader with "MS/Pro", it could most certainly be interpreted as "either MS or Pro". Still, I want the label to be as short as possible.
