cocoa - What is the usage of NSResponder's indent:?

Question

NSResponder has a method you override called - indent:, but unsure when it would normally be activated.

Answer 1

It's typically used in programming text editors to fix up the indentation of a piece of code, e.g. converting:

for (...) {
something
}

into:

for (...) {
    something
}

If you're not familiar with Cocoa Text's key binding system, see the documentation — it's pretty powerful and flexible.
