Bolshka:
Have a ton of trinkets and hate not having 'em on your hotbar? Well, my friends, make a macro that will encompass whatever trinket you have equipped! Check it out, yo:
Use Top Trinket
/use 13
Use Bottom Trinket
/use 14
Est sehr muy handy, non? To clarify, this is a script to use whatever trinket you have equipped in the upper or lower slot.
The Addon "Outfitter" or "TrinketMenu" is also useful for this. See "Addons" for information about that.
