Item

Item is a recurring command option in the Final Fantasy series that appears in every battle event. When selected, a menu will appear, listing all usable battle items; including recovery items such as Potions and Phoenix Downs.

Certain titles in the series also allow players to customize the command menu, enabling them to replace the Item command. If not careful, the player might face when trying to recover from difficult battles. Some battles are noted to have disabled the Item command at times, forcing the player to rely on Magic for recovery.

Final Fantasy
The original NES version had the Item command, but strangely enough, the only way to use Potions was with the Drink command instead.

Final Fantasy V
While most jobs have the Item command by default, even the Freelancer, the Mime doesn't, and must have it equipped if it wants to use items.

Final Fantasy VIII
Item is a junction ability that every Guardian Force has already mastered. It may be removed using the item Amnesia Greens, and later re-added using the Item Scroll bought from Pet Shops around the world.

Final Fantasy Tactics
The Chemist's job skill is Items. Unlike other games, each individual consumable items must be learned as a skill. A Chemist must spend JP in order to master these skills.

Final Fantasy Tactics Advance
The Items command set must be placed in the secondary action command slot in order for a unit to use items. The Alchemist is always able to access the use of items regardless of their secondary action command.

Final Fantasy Tactics A2: Grimoire of the Rift
The Items skillset in Tactics A2 follows the same structure as Tactics Advance.
