We should gather all the questions on where to fins strings that are hard to find. Seeing the string in action helps a lot when you are translating, but sometimes they are just to hard to find.
Each question should contain the string and it's cpp file.
(also I'd like to propose a new forum for translating, where you could put topics for each language translation and post your questions and findings there)
First question: declipper, initeffects.cpp
