Setting changed on my Ti-89 Titanium

In summary, the speaker is having trouble with their Ti-89 Titanium calculator as the insert mode has been changed to overwrite mode. They used to be able to add characters without erasing the current one, but now it erases it. The speaker is looking for a way to change it back, and Google suggests using 2nd+backspace to switch between modes. They also mention that the INS key above backspace indicates how to access insert mode.

I am not sure what I did, but a setting changed on my Ti-89 Titanium. I used to be able to go back to my input line and add new characters like a parenthesis or a missing number. This is one of the big advantages to a ti-89, however, somehow, When I go to insert new characters, they erase the current one infront of the input line. This is a big problem! How do I change it back!??

Like most word processors, the 89 can be put into overwrite instead of insert mode. Google says you can change back and forth by 2nd+backspace. INS appears above backspace to remind you how to get into insert mode (blue to tell you to hit 2nd and then that key).
