HI list, I am trying to insert a line in a document with vi. Precisely, I need to insert that line to be the first one in the document. How can I turn on/off the insertion mode in vi? Acording to instructor, we have to use the escape key to get out of the insert mode for every new line. How can I switch btw the modes in vi and how can I know in what mode is the program at? Many thanks! Ned
