i need one macro to use strong health potions when the lotter push 50+ strong health to backpack, is possible?

If amount of potions is 50 or higher and health less than 50% it will press F2 button. Just set F2 as strong health potion in Tibia options. If You want to use other hotkey: http://wiki.bmega.net/doku.php?id=virtual_key_codes

Misc.ItemCountEx(236)>=50
Self.Health%()<=50
Tibia.SendKey(113)
