emacs- Read from the minibufferr.txt

Use read-from-minibuffer to get input from the minibuffer. You don't need to initialize it separately. When calling it, a 'prompt' is required that will show up in front of the text insert area. For example:

That will launch the minibuffer with a "Search: " prompt and return the text that's typed into it.

I haven't figured out how to read one character at a time like this. The "completion" stuff provides some ways to do that though.
