Keyboard shortcut for invisible characters?

Is there a keyboard shortcut for show/hide invisible characters? I’ve tried every key combination I can think of, but haven’t managed to stumble across it. So far as I can tell, it’s not possible to add it as a button on the toolbar either, which would also be handy.

Thanks

There’s no shortcut but you can define your own ones for each application via the system preferences.

Ah, of course! Thanks, Christian.

You have to add shortcuts for both Show and Hide Invisible Characters, but prefs accept the same key command being used twice, so you can use that to toggle them on and off.
