Taking suggestions from the question: [quotations] vs. [quotation-marks]?
On the one hand, each individually suggests the right thing pretty unambiguously — “ ” often get called quotes, but I’ve never heard them called quotations. On the other hand, since they start (and mostly continue) the same way, whenever you start typing either one, both will come up on autocomplete; and then, with them side by side, the distinction should be clear even for less experienced speakers of English?
On the flip side, this similarity has the drawback that a slip of the keyboard could easily lead to mis-tagging. But I imagine that’d be a much less common source of error than misunderstanding the terminology — and also, if the terminology is clear, then accidental mis-tags will be noticeable to readers, so will quickly get corrected.
