My cursor is a blinking black rectangle. I don't know how it became that way. I want to turn it back to a blinking vertical line.

You're in replace mode. Press the Insert key on your keyboard to switch back to insert mode. Many applications that handle text have this in common.

If you happen to be using a mac keyboard on linux (ubuntu), Insert is actually fn + return. You can also click on the zero of the number pad to switch between the cursor types.
Took me a while to figure that out. :-P
