## Key Up

**post** `/computers/{id}/key-up`

Release a keyboard key that was previously pressed with key_down. The key name should match the corresponding key_down call.

**Key names are case-insensitive:** "shift", "Shift", and "SHIFT" all work.

**Important:** Always release modifier keys after use to prevent them from affecting subsequent actions.
