The "Use Item at" package command can be used to force an actor doing some motion activities. For example if you use book (and has a book) he will get a reading potion, or if you put hoe01 (and has hoe01 in inventory) he will farm the land. At the moment i have discovered the following:

Βοοκ = Reading a book
Brush = Painting at certain place
Hoe = Farming the land
Apparatus = Mixing potions
Ponder01Token = Praying
PreachToken = Preaching
Weapon = Attacks (Training)
Magic = Attacks (Training)

Do you know any other like these? For example maybe blacksmithing...? Or mining....
Jusr looking for more activities

You can look up idle anims that use objects either in the idle animation manager (gameplay>idle animations>AnimObjectAnims) or in the object window AnimObject category. There are a few anims you haven't mentioned (painting, drinking with mug in hand for example). SI adds a whole bunch of new animations, among them smith animations.
