For question mark you press Shift+7 not Alt+7. But yeah, sometimes keyboard does not have Ґ, so you must press Alt+Г. Lucky, that itʼs rare letter for mass. But it is not for apostrophe which is at fucking corner.
Ukrainian keyboard looks like on pic where blue keys. But yeah, itʼs shit. Ukrainian alphabet is also bad. If speak Ukrainian alphabet then I prefer drahomanivka where keyboard would looks like on second keyboard which is similar to Serbian but these blue are optional because џ can be дж, ч = тш and so on.
