Answer 1

You need to press i first, to enter to insert mode (when you open vi, you are in command mode by default).

Then, do your editing.

When you are done, press Esc and then type :wq and enter to save your changes.

Also note that vi is an advanced editor; if you just want to make some quick changes, an easier one, like nano, might be appropriate.
