How to use
In everyday conversation, 'key' is often used to refer to a physical object used to unlock a door or a digital device. However, in more technical contexts, such as computer programming, a key can also refer to a specific piece of information, like a password or passphrase. It's worth noting that the phrase 'key in hand' is a common idiom, but it's often misused as 'key in the hand' by non-native speakers.
