Bent,
I doubt that TranslatedStrings.txt only works for Windows.
I assume, you're working with a danish keyboard and an English version of LR 2? Is the keyboard layout below the one you're using?
If yes, download the attached TranslatedStrings.txt and put it into "/Applications/Adobe Lightroom
2.app/Contents/Resources/TranslatedStrings.txt". No file of this name should exist there already.
This TranslatedStrings.txt replaces all shortcuts with a "[" by "<" and "]" by "$".
To my knowledge, the following function are affected by the [/] shortcuts in the English version of LR:
[li]Rotate left/right[/li]
[li]Increase/Decrease Rating[/li]
[li]Increase/Decrease Brush Size[/li]
[li]Increase/Decrease Spot Removal Size
[/li]
[li]Move Up/Down in Stacks[/li]
I think Increase/Decrease Feather would also be one, but I just cannot find the syntax that specifies it.
If you're not happy with these replacements, just edit the file TranslatedStrings.txt and replace all < or $ by something else. But it is important that the special characters you chose are available without Shift or any other combined key, just on the very normal plane of the keyboard.
Give it a try!
