Throw can be applied to any wielded object. Throwing at a target starts combat. Some objects will do nothing when they hit a target. Others will explode, capture, pierce, or otherwise wound the target. Some might just break.
Throwing an object without naming a target moves it to the relevant room.
When wielding a bow, you can use the shoot command instead.
The command only looks at objects you are wielding. So, if you wish to throw 'dagger 2' in your inventory at a target in the same room as you, use the commands:
wield dagger 2
throw dagger at TARGET
