Re: Console Command dosen't shows up/work
If you have a non English/US keyboard and if you open the "BIOInput.ini" under "Documents\Bioware\Mass Effect\Config" and add "ConsoleKey=TAB" to the "[Engine.Console]" section
and save the "BIOInput.ini" afterwards, the console will work on both the Steam and the Origin versions of the Game.
Any key that is not bound to a in game action and not exclusive Windows bound will work too, as long as you enter the correct key name into the "[Engine.Console]" section of the "BIOInput.ini". You can test that with the "+" key of your keyboard set to your native language. ConsoleKey=+
Setting a second keyboard and removing the native keyboard from the Windows settings is not necessary.
