Thanks for the help, but I don't understand it completely. I have LR5, in English, on a Mac. I checked, and there is already a "en.lproj" folder in that "Resources" folder. But there was only one file in there, called license.html.
So, I made a new "TranslatedStrings" file, in that folder. But on a Mac, you can't save it to .txt, only to .rtf, or am I missing something?
Right now, I've put that "TranslatedStrings.rtf" in that "en.lproj" folder, but I don't know what I have to do next... The tutorial says I need to change the shortcut in that file (e.g. “$$$/LibraryMenus/MenuShortcut/DecreaseRating=[“ and change it to “$$$/LibraryMenus/MenuShortcut/DecreaseRating=;”), but as I just made that .rtf file, it's of course empty. I wouldn't know what I have to change or so...
So, please, can you help me a little bit further? Would be very nice!
No problem at all, the extra information helps!
You'll need a plain text editor to save a .txt file- TextWrangler is a freebie in the App Store which works great. http://www.barebones.com/products/textwrangler/ Or in TextEdit, go to Format menu > Make Plain Text and then it'll let you save it as a plain text file.
You'll need to look at one of the language files to find the right line to copy into the empty TranslatedStrings.txt file. I'm sure your French is better than mine! I think the line you need is "$$$/AgDevelop/Menu/View/BeforeAfter/Before/Key=Shift+s" - replacing the French shortcut Shift+s in that line with your chosen new shortcut. Paste that into the TranslatedStrings.txt file, save it in the right location, then open Lightroom and hopefully you'll find your new shortcut works.
Since you're on a Mac, the alternative is to use the OS System Preferences > Keyboard settings to assign a custom shortcut. Try the TranslatedStrings bit first though, since we've got this far and I know that works!
