Use matching structure instead of the next identical character.
Before this lesson: Choose the whole pair.
% on a bracket moves to its matching partner, including nested pairs. d% removes the pair and its contents. A character search only finds a character; it does not understand the matching nesting. Inspect the desired result before including delimiters.
On the opening parenthesis in outer(inner(value)), % reaches the final closing parenthesis, not the inner one.
