I'm not sure I understood what you meant about the lactation. I'm fairly certain I've saw somewhere you can use the lactation spell a second time to turn it off ; so I assumed the spell act as an on/off switch for milk production (as in, it add or remove the milk action), but again the spell does not seem to be castable a second time
(I have no clue where i've read that lactation thing, and hope I was not just dreaming)

As for the shift key, on some non-english keyboard (let's take azerty as an exemple), you need to type shirt + & key to type "1".
Using shortcut that way (with shift held down) often hide the chatbox when picking a choice (this happens fairly often in sexy encounters).
It's also a pretty natural things to attempt when you use shift to look at a shortcut.

On that note: it seem shortcuts works on the key location on the keyboard and not the character itself, which make pressing the "&" key work to access the "1" shortcut (since it's the same location on keyboard) ; which entierly circumvent the bug.
It also means some shortcut are badly placed on other layout (ex: q and a are swapped on an azerty keyboard), but I dont think it's worth trying to correct the shortcut's display for all keyboard layout, unless an automated way to do it exists.
