Sorry, title limited on what I could type. I just got this calculator and am having two big issues with it. 1) I cannot figure out how to reuse my most recently typed equation. For example if I type in a insanely long multiple variable equation and evaluate, the only way I can figure out how to get it back is to type it all out again, if I want to change something and re-evaluate. On my Ti 89 I could just do 2nd + Entry. 2) How can I disable the touch pad? I have no desire to use it and I see no reason to use it, and it is causing me to misclick through the menus way too often.
