"Switch to English" shortcut

Switching from my localized version to English language takes as little as 7 actions - and back to German again another seven. The result is that when asking questions in the forum, I often did not switch to English and do not know the proper English words. Even worse: Sometimes I would need to switch between German and English several times to make really sure I grabbed the right item.

I asssume that all of our daily life would be a little easier if there were a one-click-shortcut “switch to English” and “switch back”. Requesters could create their forum entries more precisely and quickly, and - this is much more important - people willing to answer are more likely to get properly worded requests.

Please let me know if such a feature already exists.
