For ease of use, Avalon provides you with several commands to list specific types of possessions. KEYLIST, as mentioned above, lists your keys. In addition to this you can use POTIONLIST to list the alchemical potions in your possession, RUNELIST to list the alchemical runes you have at hand, HERBLIST to list the herbs you hold, and POISONLIST to list the poisons you have in your inventory. MAGICLIST will give you a list of all magical items you hold once you have attained sufficient level in the Itemlore skill, DEMONLIST will list your demonic entourage if you have the skill of Demonology, and ARMOURLIST and WEAPONLIST give lists of all armour and weapons respectively.
Since Avalon gives every item a unique number for easy recognition, most of the above commands provide you with these numbers too. To find out the unique number for any of your items not in these lists type INFO followed by the item. INFO will cycle through your items so that if you have a number of any specific type of item, you can find out the unique number codes easily.
