I am writing a report for psychology. It has to be written in APA style which
stipulates that the heading must be centred and the text underneath must be
aligned left. The text must follow on the next line below. When i press enter
it seems to jump down 2 lines and allows me to align left, but when i press
shift + backspace key the text centres again. I've been trying to get around
this for over an hour and i can't work it out! I know it's a paragraph tool
but is there anyway of making the heading different to the text? Thanks,
Elisha
