Ok this is a small tip to increase lockpicking skill, earn a little extra gold and sometimes get a green or blue item.
create the following 2x macro
#showtooltip Garrote
/cast Pick Pocket
/cast Garrote
#showtooltip Cheap shot
/cast Pick Pocket
/cast Cheap shot
When you use any - if the enemy can be pickpocketed - they will be - or it will just say ' has no pockets'
I know its a really small tip but it heped me alot leveling my rogues skill
