Actually, I just found this on the Harmattan Bugzilla - it seems that bluetooth keyboard support is a not-officially-supported gconf setting that someone snuck in (akin to landscape homescreens): There are some glitches where vkbs have to stay open to avoid losing focus (it doesn't change the same flag as having the hwkb open on the N950 I guess) n.b. haven't actually tried this myself, just reading bug reports!
