 #showcooldown BagId slot  <--Shows an item and its cooldown by bag slot
 #showcooldown InvSlot     <--Shows an item and its cooldown by inventory slot

== Aliases ==
:none

== Arguments ==
:;spellname
::Name of the spell of whose icon/cooldown is to be shown
:;itemname
::Name of the item of whose icon/cooldown is to be shown.
:;[[BagId]]
:: The bag the item is in (0 is backpack, etc...)
:;slot
:: The slot number, starting at 1, of the item you wish to show
:;[[InventorySlotId | InvSlot]]
:: The slot on your character in which to show an item.

== Notes ==
:Selecting the "?" icon will use the icon for the spell/item/slot. This can be overriden by manually choosing an icon.
:If you don't know the spell, don't have the item, or the position you specified on your character or bag is empty, the button will show the default "?" icon.
:Other data affecting the button's appearance will be pulled from this as well, such as the green border around equipped items, the number of items you have, the number of reagents for the specified spell you have, etc...
:The click action of the button will not be affected by this, you still need to use the commands to make the button do something.
:Any successive metacommands to define the icon or tooltip will be ignored
:This does not affect the tooltip of the macro. If you want to specify both the icon and tooltip, you should use [[MACRO metashowtooltip|#showtooltip]].
:Omitting arguments to this metacommand will have no effect. By default, the UI will pull information from [[MACRO cast|/cast]], [[MACRO castsequence|/castsequence]], [[MACRO castrandom|/castrandom]], [[MACRO use|/use]], [[MACRO userandom|/userandom]], [[MACRO equip|/equip]], or [[MACRO equipslot|/equipslot]].
