To use backstab, Hide in Shadows and stand behind your opponent. Your *first* attack will be a backstab.

Hide in shdows is pretty simple, just use it *before* you go out exploring, you cant activate it in LoS of an enemy.

Pickpocket, same as disarming traps but you click on a person instead of a trap. Not the msot sueful, but there are some sweet items you can get like this.
