Scott,

If you are using "vim" (do check my last message), try hitting
the Escape and enter the following command:
:set ruler

(Don't forget the ":" in front of the "set" command!!!)

This should display more relevant information to you, especially
the "-- INSERT --" signal when you are trying to enter text. If
you need something easier to use than "vi", please try to install
"nano" -- it's the GNU clone of "pico" (try this as well) and a
very, very simple editor to learn, as all commands are displayed
on the last two lines of the screen.

If you'd like to learn vi, just start by using the reference text
attached to this email. It's fairly short, but, I hope, informative.

Hope this helps!
