Right now, if the shortcut key is defined as lowercase, we return it as such. Convention in every OS we ship on is uppercase. The module should probably deal with that itself. Patch coming up soon. NB: slight worry: what does .toUpperCase() do for e.g. non-Latin-based scripts, and what is convention there?

Random spot-check seems to indicate this should generally produce the desired result. However, see also: http://stackoverflow.com/questions/19286435/javascript-touppercase-mess-up-in-chrome-for-latin-character . An alternative solution would be WONTFIX, and making l10n teams update their strings to uppercase where required.
