I’ll look into these!
Regarding lactation: lactation being off does not make it so you can’t lactate, it just stops you from regaining the ability to lactate over time, if that makes sense. So it’s possible to shut off lactation, and still be able to lactate one more time afterward.
I’m not sure I understand what you mean about the shift key. Shift should just show the hotkeys. You are not supposed to have to should it down to activate the hotkeys. Is that what’s happening for you?
