Very convenient QTranslate

lingvo, stardict.

In foxit reader the text looks like text and such things as lingvo pick up text under the cursor. But acrobat reader did not work.

Like they can't Rob the text on the screen that is displayed Acrobate Reader om directly. Stardict requires some kind of plugin. There is a programme of Aqua Deskperience, so she drags the text everywhere, but it is not a translator, but it can be configured to immediately transmit the request to third party site for call transfer. Version trial, but... he who seeks will always find.
