Minecraft wiki entry for Time-saving_tips, associated text: Similarly, some recipes can be overlapped, so that you can make two different items at once with two quick clicks. You can overlay a shovel (and/or hoe) recipe over that for a pickaxe or axe: stack the extra sticks in place, and add an extra block or ingot at top center (and for a hoe, top-side). When making armor, boots or helmet can likewise be overlaid over pants or chestplate (and/or over each other).
