If I'm not mistaken, the French keyboard is arranged differently than the English keyboard. There are also some letters with accents not used in English. Since you don't speak French and presumably would not be typing in that language, you probably ought to pass on it.

It turns out that the French keyboard as used in France is indeed different layout. The Canadian French keyboard, however, is nearly identical to the English one. Learn something new every day.
