Currently, if I want my beer "today" I put the gas into the out tube at the desired target pressure. I then rest the keg on my lap and gently rock it for about 20 mins, until I don't hear any more bubbling. Then I let it sit for a few hours.
Is there an easier way to carbonate quickly? I hate having to disconnect my gas line to get the keg out of the fridge, and I hate sitting on the floor treating a corny keg like a baby.
