when you first get into the screen that you want to edit, look in the lower left hand corner and notice the character there. if it changes when you press i, then you should be able to edit. when you're done, watch that character (it usually changes from a hyphen to an I, and then back for me), then push esc. after that i type these to save and quit
but it will look like this, substituting the hyphen and the I with
always watch those characters in the lower left, they "inform" you of your status, so to speak.
then push enter and the file turns into the regular terminal characters
