Okay
What made me think that writing a letter could help, um, yeah I don't know. It's just weird imo that they lock everything down without any respect for the user rights. I'm sure the community has done a lot for TI in direct and indirect ways.

I see what you did there. You should write a letter to TI, your arguments are pretty good.

Hmm, yeah. Some form of the Axe getkey would be cool And is pretty much possible I guess. (Axe has getkey(keycode) just like basic but 120 times faster).
Also no key delay function would be cool.

OK

This is really cool. I hope TI will turn more and more to the community again. I seriously hope they improve Lua. (Isn't Lua on the nspire about as fast as asm on the 84+ series?)

Hmm I wonder, why is the key layout upside-down? That can be easily turned imo?

Well I read the first part of it and I really like the style ^^ however isnt the ans varable accessible by pressing [2nd][0]? Changing that now.
Edit: I also changed "TiLp" to "TILP". Are there any more things you want in it? I could help writing a bit. Maybe on error messages.
Also, is this meant to be a programming tutorial or a tutorial on how to use your TI-83+ series calculator?

Wrong timestamps!
Which now make you lose.
J/K I wonder where the sigmas went. Remembers me of the april 1st logo joke...
