Questions people ask
How do I use regular expressions?
Tick Use regular expression and write a pattern such as (\d+)-(\d+). In the replacement, $1 and $2 stand for the groups, and $& for the whole match.
What does Whole words only do?
It stops cat matching inside category: the match must have no letter or digit directly before or after it.
The page slowed down. Why?
Some regular expressions can take very long on large text, which is a property of the pattern. Simplify the pattern or use a smaller piece of text.
Is the original text changed?
No. The result appears in a separate box, so you can compare it with what you pasted.
