Hello we have a form in which the users enter the data in Greek language. In
some fields the data must be entered in english (e-mail field etc) Is it
impossible every time they enter a specific field the language to
automatically be changed from Greek to English? and when they exit that field
to have it turned back to the previous selection? Note that Greek and English
are the two languages in every computer.

So I just need to switch languages when entering specific fields. Is it
possible?
Thank you in advance.
Dimitris
