I needed to go to the TSA web site for a question (that question is trivial) ... while I was there, I came upon the TSA FAQ for it's screening process (I put a link down at the bottom).
I was surprised to find that some of these are "Frequent" questions. And so, what follows are the FAQs, under the section "Screening", in the order they are listed ...
Q. Will I be delayed during screening if I am carrying large amounts of cash?
Q. Can I leave the secured area of the airport during my layover?
Q. Can I carry tranquilizer darts for hunting?
Q. Will going through the advanced imaging technology have a harmful effect on my unborn child?
Q. What should I do if I am not offered the option to have a pat-down instead of going through advanced imaging technology (AIT) equipment?
Q. Is AIT safe?
Q. Are car parts allowed in my carry-on baggage?
Q. What time will TSA staff be at the airport if my flight is early in the morning?
Q. Do I need authorization to carry medication that will be delivered to another person?
Q. Do I need special documentation to carry surgical tools?
Q. Can I carry pills in a small plastic bag or a daily dose container?
Q. Can I take food that is frozen?
Q. Is there a limit to the amount of cigarettes I can carry onboard?
