Frequently asked questions
What is natural sort?
Natural sort compares numbers by value, so "file2" comes before "file10". A plain A→Z sort compares character by character and puts "file10" first.
How does case-insensitive sorting work?
With it on, "apple", "Apple" and "APPLE" sort together using your language's alphabet rules (accents included). With it off, lines are compared by exact character codes, so all uppercase letters come before lowercase.
Is the shuffle truly random?
It uses the Fisher–Yates algorithm, which gives every ordering an equal chance. Click "Shuffle again" for a new order – good for raffles and randomising quiz questions.
