Find and Replace

Find a word or phrase in your text and replace every occurrence at once, with whole word, case, and regular expression options. A whole-word option is included.

Find and replace rewrites every occurrence of a string in a text. A whole-word option avoids mangling a word inside another, and the regular expression option covers the cases a plain search cannot, such as collapsing repeated words.

Questions about find and replace

What does whole word mean?
It only matches when the search text is bounded by spaces, punctuation, or the ends of the text, so cat will not match concatenate.
How do I use a regular expression?
Turn the option on and write the pattern without slashes, for example two backslash and w plus a plus sign for repeated words.
Is the search case sensitive?
Only when you turn the option on, so The and the are treated as the same word by default.
