Scrolling or using the bottom arrows of the pop-up box will cycle through available recipes of that method. Pressing the Recipe key (default R) when hovering over any item will bring up recipes that include that item. For example, wool will change its color and ores will show other variations of the same ore by using Forge's Ore Dictionary (this cycling can be stopped while holding Shift).
When a recipe can be made using multiple types of the same item, the ingredients will cycle through the available subtypes. Recipe view shows all the ways to craft that item, be it with a Crafting Bench, Furnace, Brewing Stand or other custom crafting Inventory. At any time, closing the NEI's pop-up box can be done with ESC key or Inventory Key (Default, E).
