more calculator stuff (odd things)
the two biggest things i noticed were these:
btw i have a TI 84 Plus Silver Edition (new) if you didnt know (very similar to the TI 83 series)
-when i would go to the catalog (2nd, 0) i could see the syntax of using a selection by pressing "+", and it just stopped doing that for no reason
-just today i was scripting some stuff when out of nowhere, i could make lowercase and capital letters and i could alternate by pressing the "ALPHA" button. just yesterday if i pressed the "ALPHA" button, it would only do capital letters, and if i pressed it again it would go back to the normal cursor. does anyone know how to change these options?
