<ignore>I see SL has some kind of built-in OS support for smart (typographer’s quotes). While it’s clearly possible to hand-type them, the widespread availability of smart quotes in other apps (and the confusing correlative that in some of them using the alt-shift key combos then reverts back to the straight variant) means life would be much simplified if I could rely on similar behaviour in OO.

Any chance of enabling</ignore>

Oh. Ignore me. Already possible. Control-click on text and go to Substitutions > Smart Quotes in the pop-up.
