Macro To Use An Item

[Darger]

I play an OT and i have a healing rune not listed under the healing portion of the bot. I have the ID of the item but im not sure how to set my character to use it.
I tried the following:

100 {Heal} Self.Health<=3000 Hotkey.Use(3194)

Or

100 {Heal} Self.Health<=3000 Tibia.KeyDown(f2)

Both didn't seem to work (I have the rune hotkey to F2 if that helps.
