I lay the bolt on a padded table facing to my left. I take my right hand and hold my dental pick (or jewler's screwdriver) and use the bottom of the heel of my right hand to keep the bolt from moving. I pry back the extractor pin and hold the bolt down with my right hand and use my left index finger to pry down the extractor and then lift it out of the slot.
I'm ambidextrous so it may be a little easier for me.
