Understanding the Options
| Option | What It Does |
|---|---|
| 🔍 Case‑sensitive | Matches the exact case of your search term. “Hello” will not match “hello”. |
| 📌 Whole words only | Only replaces complete words. For example, “cat” will not match “catalog”. |
| 🧠 Regular expression (RegEx) | Enables advanced pattern matching. Use patterns like \\d+ for numbers or ^https?:// for URLs. |
Regular Expression Cheat Sheet
When you enable Regular Expression (RegEx) mode, you can use these powerful patterns:
\\d– any digit (0–9).\\w– any word character (a‑z, A‑Z, 0‑9, _).\\s– any whitespace character (space, tab, newline)..– any single character (except newline).^– start of a line.$– end of a line.a|b– matches either a or b.+– one or more of the previous character.*– zero or more of the previous character.{n,m}– between n and m repetitions.

| Standardizing date formats | RegEx: (\\d{2})/(\\d{2})/(\\d{4}) → $3‑$2‑$1 |
