Umm... is there an easier way to access functions than going through the entire catalog?

Well when you put in a letter it goes to that letter

If you mean editing a function you last edited: [2nd] -> [APPS]
If you mean running a function you last ran: look through the history.
Running a customized function: [APPS] -> [F4]
Otherwise, you'll have to do ti the hard way.

Oh, if you just want to type in a predefined function, you can use Perfection's tip, or you can just put on the Alpha-lock and type away.

He makes graphing Fun! 
Everybody who takes pure math at our school is required to have one, or an equivalent.

My sister has a Ti-82. I'm enrolled in geometry (hell hell hell!) and my teacher has already sent home a letter, for Algebra 2/Algebra 2 Trig students to buy Ti-83s. They say that Ti-82s aren't useful enough (can't graph inequalities) and that if you get a higher calculator, they can't help you because they're not familiar with it.
Also what's with the Ti-92? At our school you're not allowed to have it unless you're in calculus.

Chances are that the teachers know nothing about technology anyway. Helping yourself is always the best bet.
The (discontinued) TI-92, (soon to be discontinued) TI-92 Plus, and the (new) Voyage 200 all have qwerty keyboards. Therefore, they can't be used in ETS tests. Yes, this regulation is either dreamed up by some idiot or heavily subsidized by TI. It doesn't make sense at all since the TI-89 really don't lack any functionality they have. They should have made the breakpoint at whether a calculator has a CAS. Your school is outlawing them because they are too powerful though.

Got my trusty old Casio fx-85VH, simple but good calculator and with its practical plastic casing and solar power it will probably survive humanity and still be operational.
If I want to calculate and display complicated things, I turn on my real computer and use Excel.

There is no TI-82 Plus.
Right. Sorry!
Well, that pretty much reflects my interest in that kind of stuff - I just got one, and done. Well, then it's a Ti-83 Plus, even though I don't have it with me here to check. And no I don't miss it, and no I don't polish it every day.

Good. Now go away and tell me what animal the graph of x=89y+87.446-93x^3y*56y^4 looks like.

Simpler terms, please?
What's ETS? CAS? Qwerty keyboards? And how are they too powerful?

Educational Testing Service, which administers the AP exams and SAT I and IIs, and therefore pretty much dictates what kinds of calculators are allowed for math courses.
Computer Algebra System, about which I'm not sure as my TI-83 Plus doesn't have one.
Qwerty keyboards allow people to rapidly enter test questions into the calculator's memory so they can be sent elsewhere to furnish the next round of student's with questions that are like the ones they will befacing next year. But ETS releases the AP exam questions anyway, so I'm not sure why they care.
Basically, the TI-92 is so powerful and versatile that it could do your whole AP Calculus BC exam for you, and that is why it isn't allowed.
