When entering text in a Rich Text field it is sometimes desirable to have a soft return — ie. a simple line break within the paragraph rather than starting a new paragraph. In many situations (including EllisLab's own forums) a shift-return keyboard combo will give this result — but not in EE's RTE, where it starts a new para.
Typing <br> will generally achieve the desired result (although it's clunky and sometimes needs the entry to be submitted more than once before the line breaks registers as behind-the-scenes html). But if clients want an RTE field it's generally because they don't want to be typing HTML elements into their text — certainly not to achieve something as basic as a soft return/line break.
I'm sure that it is possible to create an RTE button for this but that process is not particularly simple for non-developers, and really shouldn't be required for such a basic function.
Am I missing something? Or is there really no simple way to insert a line break into a paragraph in the RTE?
