Find & Replace

Search runs on a byte-level scanning engine that covers ten gigabytes in about a second — and every count it reports is exact.

The find bar

Press ⌘F. Matches highlight throughout the document as you type, with a live counter and, on big scans, a progress readout ("Searching… 42%").

160,846 matches in an 8-million-line log, found in about a quarter of a second. Enter walks matches; the current one gets the ring.

• Return / ⌘G — next match. ⇧⌘G — previous.
• Aa — match case. W — whole words. .* — ICU regular expressions.
• \n — escape sequences: \n \t \r \0 \\ \xHH \uHHHH expand in literal queries and replacements, so you can search across line boundaries.
• The clock icon recalls recent searches.
• ⌘E uses the current selection as the search term.

At scale: finding all 1,613,344 occurrences of a term in the 10 GB benchmark log takes 1.3 s; a five-way regex alternation with 5.6M matches takes 2.1 s.

The same find bar against 10 GB — 1.61 million matches, counted exactly.

Replace

Press ⌥⌘F for the replace row.

Replace the current match or everything at once. Regex mode supports capture-group templates in the replacement.

Replace All is a single bulk operation, not a loop: replacing all 1.61 million matches in the 10 GB log takes 1.7 s, lands as one undo step, and the document is fully re-indexed the moment it returns. Very large batches (about a million sites and up) can exceed the undo-history memory cap — Caxton tells you rather than guessing.

The Advanced Find panel

Everything in one panel: search history, all options, Count, Find All, Bookmark All, and both replace actions.

• Count — exact match count without moving the cursor.
• Find All — every match in the results panel, clickable.
• Bookmark All — drop a bookmark on every matching line.

Find in Files

⇧⌘F searches across files on disk without opening them, streaming results as they're found.
