Why keyboard shortcuts don't work on non-US layouts and how devs could fix it
There is also a whole slew of issues with Polish characters. Polish keyboard setup relies on "right-alt" and a letter to get it's diacritics variation. Ie: 
'ą' is 'right-alt'+a<p>Windows for backwards compatibility reports 'right-alt' as 'alt+control'.<p>Many applications developers assign key combos with no negative checks. So 'ctrl-s', typically used for save gets triggered when user wants to type 'ś'. To repeat, "right-alt"+"s" is reported as "alt"+"control"+"s", which triggers crappy "control"+"s" checks.<p>Similar scenarios happen many places that check for 'alt'+'letter' without checking if control also is not pressed.<p>Microsoft thread for team user voice issues on this <a href="https://microsoftteams.uservoice.com/forums/555103-public/suggestions/32265802-alt-a-and-alt-s-affecting-polish-character-for-%C4%85" rel="nofollow">https://microsoftteams.uservoice.com/forums/555103-public/su...</a><p>or Medium's developer talking about 'ś' and 'ctrl'+'s'.
