“得心应手”，汉语成语，意思是心里怎样想，手里就能怎样做（what the heart wishes one's hands accomplish）。比喻技艺纯熟，心手相应，可以翻译为“with facility，with high proficiency”。与英文俗语“in one's element”意思相近，表示“in a place or situation where one is comfortable and does well”。
- 他画起山水画儿来得心应手。
He paints landscapes with great facility. - 我的继母得心应手地料理着一切。
My stepmother was in her element, organizing everything.
