Press 'a', 'i', 'o' to open in append mode(though they have different meaning to compiler)
press "Esc" button to leave the append mode and returns to VI command mode (Not returns to shell)
press
":wq" or ":x" to save the modifications on the file and returns to shell
":q" to close the file without saving the modifications and returns to shell
to copy the content select the source using mouse by holding left key
to paste the content right click on the editor. it appends the buffer (Copied data) to file at the cursor.
