Answer 1

vi can be horrible the first times (like beer). But after some time it can be your friend (beer again).

Basic commands:

• i start writing
• Esc back to commands
• dd delete a line
• o start writing after current line
• :wq from commands saves and quits from file
• j/k move cursor down and up (respectively)
• h/l move cursor left and right (respectively)

Here you have all the possible commands:

Answer 2

It seems like you are using Vim if you say o adds a new line. First press the ESC key to switch to normal mode, then use dd to delete a line.
