Inclined to disagree - depends on your keymap and software you use. If I were to add keyboard shortcuts to my program I'm sure as hell not gonna use a key that I can't get to on my keyboard.

On German keyboards it's even 'worse' though. Because ;, [ and ] are used for ä, ö and ü, [ and ] are Strg + ⇧ + 8 and Strg + ⇧ + 9. Same for { and }.

(Strg = Ctrl)

So any keyboard shortcut involving those and ⇧ or Ctrl is pretty much impossible.
