Line break v. paragraph

[tom]

in some instances a line break is more appropriate than a paragraph, yet there is no method other than to open 'source' and edit the html.

A possible solution would be to have the enter key by default create a line break with the first push, then a paragraph if hit twice.

You can use Shift+Enter to create a <br>.
