Minecraft wiki entry for Beginner%27s_guide, associated text: Pro tip: On standard keyboards, the Q key is right next to the movement keys. This makes it very easy to accidentally throw away the item you're currently using, which may be a valuable tool. Many players prefer to change the "throw/drop" function to another key, such as O or K. All of these controls and more can be viewed by pressing Esc -> Options -> Controls.
