ok, so I was going to say "not enough information", having stared at the Inspector bar for 10 minutes.

Eventually it occurred to me that maybe I hadn't actually started to edit the text of interest. So if you're like me and haven't figured out why you can't see the line height control, get in there and start editing the text first. It isn't enough to just select the text object (but it should be, hint to OG folks -- otherwise I can't change line height on multiple objects, can I?).

This is why it's nicer to have the command available all the time, not just contextually.

P.S. to warrenn -- I've been enjoying learning from all your questions, which have been exactly the questions I've had over time. I hope your stencils get posted!
