You should have a key with Alt written on it (the option key) on the bottom left of your keyboard. Hold it down and click. Hope this helps!

This question is off subject here but I wished you could do this as well mainly if the order was not sequential as you have it. Not sure, maybe a loop could handle it. I'm sure there's something... but I will say that your example could be done like this...

// Pulling out a range works like this // The half-closed range operator (1..<3) includes 1, up to but not including 3 (so 1-2). // A full range operator (1...3) includes 3 (so 1-3).

// So it would look like this: todo.removeRange(3...6)
