I’d like to take a moment to appreciate how Linux keyboard layouts fill unused combinations like AltG+K for Polish with characters that might be useful (the ellipsis character in this case). On Windows if I wanted to insert °, …, ™ or a non-breaking space I’d have to memorise its alt-code or create a custom layout. (Which is about as well supported and easy to do as you’d expect from Windows customisation.) On Linux I just type AltG+Shift+0, AltG+K, AltG+Shift+T or AltG+Space respectively, because they’re part of my layout out-of-the-box.
