There is no reason that if I am currently in France and my parameters defines a french keyboard I have to be redirected to the corresponding "help". There are several reasons :
- I can be interested in reading help in English (or another language) while I am French, particularly if I participate to "help" development (for my own I can read and translate French, English, Spanish, Italian and not lost in German or Deutsche contents and use efficiently Google translation - able to check validity in a context)
- for forum or debug there are problem that can be specifically linked to a language or others must be treated in English.

The solution is to define a "context language" which can be by default the "interface language" with a proposal to automatic or manual switch.
