I don't know if this is just my calculator but with micropython 1.3.1 I can't exit the program and can only leave if I remove my calculator's batteries but when I use micropython 1.3.4 and does micropython on the ti nspire have any library built-in or library that you can download because I have a lot of programs that I have written that need libraries that I can't call on also in micropython 1.3.4 none of the shifted characters like shift and period is colon and I can't get a square or curly brackets with ctrl and shift
