Lately I've been sugar-priming my kegs. Let them sit for a couple weeks just like bottles. Works great and no worries.

Used to hook up keg every day and put about 40 psi on it. After about a week it should be carbonated depending on the head-space. Less head-space equals longer time to carbonate with that approach.

I set it to 40psi, and shake every once in a while for two days, then go to style dependant psi, on the fourth day, I'm ususally good.

One reason not to shake carbonate your beer(I don't); from a BYO article:
 "Lastly, homebrewers who keg their beer should be aware that foam positive molecules can get “used up” when foam is created. Thus, if you shake your keg to carbonate it, you may be dipping into your pool of foam makers for your beer."

Palmer and JZ also say this.  I still do it.  And nary a problem with head retention/creation.  Most times I can float a bottle cap onthe head.
