I have Windows 7 and Windows 8.1 in Portuguese and honestly, after over 13 years using computers, I still bang my head into the wall with the default shortcuts.
Just to showcase the madness:
Every program uses Ctrl+A to select everything. The Portuguese version uses Ctrl+T. The shortcut Ctrl+T is used to open a new tab, but Portuguese IE uses Ctrl+S. Normally programs use Ctrl+S to save, while the default on Portuguese is Ctrl+G.
I'm honestly tired of this and it really hurts usability especially on Windows Explorer. Is there any way to put decent shortcuts into those programs?
