Tab — accept the completion that matches, reject the one that drifts
Editing in flow with Tab suggestions
DoRename the prop to matchCount in the interface — one hand edit, so Cursor has concrete local intent.
SeeA gray ghost line appears under the function signature: the same rename, proposed at the next occurrence.
DoPress Tab to accept, then Tab again at the next occurrence.
SeeThe rename lands everywhere you meant it, and the ghost chains from edit point to edit point — your hands never leave the keyboard.
TypeTab now proposes renaming the CSS class `results-count` too — a stylesheet contract your rename never included.
DoReject it and keep typing; that suggestion changes intent instead of preserving it.
SayWhy keep two and drop one?
SeeYou can name the reason: matched intent vs. changed intent. And if you ever misread one, takes it back — Tab mistakes are cheap when you catch them in review.
