Hey there,
I farmed all my lockbox for Ravenholdt on my rogue and i made some nice script for it.
You have to use AutoHotkey. Its not an hack, its a legal program to run script on your computer. What my script does is simply every time you mousewheel up your script will generate the TAB and hotkey 2 on your computer. So ingame just make sure your pickpocket is under 2 and make sure tab will do the default tab target. Then just take the script i will post below and start spamming your mousewheel ingame. You simply have to walk close to stuff and your mousewheel up will target every target and pick pocket them ( make sure you have autoloot on). You can also get a lootfilter addon and you will be looting like crazy with no effort and in not time.
Enjoy this
Btw : TB pickpocketing with this is good extra money
