Fired when any actionbar slot's contents change; typically the picking up and dropping of buttons.

On 4/24/2006, Slouken stated "ACTIONBAR_SLOT_CHANGED is also sent whenever something changes whether or not the button should be dimmed. The first argument is the slot which changed." This means actions that affect the internal fields of action bar buttons also generate this event for the affected button(s). Examples include the Start and End of casting channeled spells, casting a new buff on yourself, and the cancellation or expiration of a buff on yourself.

This event fires whenever an AddOn is loaded (fires once for each AddOn loaded if multiple AddOns are being loaded), whether that is during the inital Loading Phase or when an AddOn is loaded using the LoadAddOn("addonname") or UIParentLoadAddon("addonname") function.

It appears to fire twice, but the reason is unknown.

This event is fired when the auction interface is first displayed. This is generally done by right-clicking an auctioneer in a major city.
