Using NEI
Clicking the box at the bottom of the screen in an inventory (any inventory) allows for the searching of items. Hovering over an item and clicking "R" (for Recipe) will display that item's recipe. Clicking "U" (for Use) shows what that item is used to create. Clicking the search box twice allows search for an item in a Chest or other inventory; the items that match will have a golden outline, and other items will have a gray outline. Double-clicking the box will turn off the search mode.

Dumps
In the left-bottom corner of the inventory is an Options button. Clicking it, and then clicking Tools, and then Data Dumps will give a GUI that allows dumping of Item, Block, Potion, Enchantment and Biome IDs, as well as Item/Block textures. This will dump them into the minecraft folder, under the folder "dumps".
