Ctrl+F7, Review ▸ Thesaurus and the context menu open one dialog: the
word at the caret, the sense groups it is in, click one to replace it,
and a box to look up any other word. The data is MyThes re-packed to one
group per line (de 3.0MB/37k groups, en 6.7MB/143k) — the format repeats
every group once per member, ten times the bytes. Loaded on first use for
the document's language and scanned, not indexed: ~4ms a lookup, where a
word→group index measured ~100MB of memory against the text's ~8MB.
