As far as I can see, no keyboard shortcut exists yet to toggle (multiple) selected furniture visibility.
Could be very efficient, compared to clicking in the item list, e.g. to temporarily hide various pieces of furniture, even across rooms and levels, for a furniture-free photo shoot.
Although it might be more difficult to make them visible again, since you 'lose' the selection. (Except if you take no other editing actions in between and can use Undo.)
Come to think of it, an already usable alternative is to temporarily group the furniture items, and toggle that group's visibility.
Thanks hansmex, that's a great idea! Will use it. One downside is that it doubles the number of levels (if all have furniture); that can get unwieldy.
I still figure a visibility toggle shortcut might be useful, in this case and others, e.g. to quickly 'ghost' high-placed furniture to rearrange furniture underneath.
