I agree. Using shortcuts on a German keyboard can be a paid. Mine has no bracket keys. I've though of buying a US keyboard on my next visit but then I'd be missing the Umlaut letters - not to mention, that I've gotten used to the (different) positions of the letters "z" and "y".
I've played around on the keyboard searching for alternative shortcuts but I've also messed up settings more than once that way and spent a great deal of time fixing what I initially didn't know I'd changed. I've given up on most shortcuts and mainly only use "g" for grid view, "d" for develop and "y" for before & after.
While I enjoy all lula tutorials and Michael's & Jeff's explanations have been a great help (and very interesting and entertaining), most shortcuts they mention don't work for me. I wonder what it's like to use a Chinese, Japanese, Hebrew,... keyboard?
