@Knight231, To look behind while moving button R should do the trick.
If you selected non dialogue based pickpocket in options menu, right mouse button should perform it but you have to do it while in crouch/sneak pose behind your target for first 100 successful attempts after that you will become master thief and just standing behind your target will be sufficient.
Most of keybindings that involve two buttons can be found in Help menu press H (this includes npc resurrection scroll BoD ) all combinations are left shift+ some other button.
To use BoD you have to focus on dead npc (stand in a way that you see its name) and Lshift+ Numpad 9
