Frequently Asked Questions About Find and Replace
What is regex (regular expression) mode?
Regex mode allows you to use pattern-based search instead of exact text matching. For example, \d+ matches all numbers, \s matches whitespace, and [aeiou] matches any vowel. This is useful for complex find-and-replace operations.
Can I replace across multiple lines?
Yes. The tool works on the entire text including line breaks. In regex mode, you can use the s flag (dotall) to match across multiple lines.
How accurate is the match count?
The match count shows exactly how many occurrences of your search term exist in the text. In case-sensitive mode, only exact case matches are counted. In regex mode, each pattern match is counted.
