Võtmeteks

Could you clarify what Võtmeteks refers to? I don’t have enough context to identify a real, widely recognized subject by that name. If you want, I can draft a concise, neutral wiki-style article for Võtmeteks as a fictional concept, a place, a work of art, or an organization. Alternatively, if you have a real subject in mind, please specify its category and any source or context you’d like included.
