Word translation tool with mouse click?

Question

I am learning Spanish. And I read texts in Spanish on my computer (normally PDFs) where I want to translate words I don't understand with a click of my mouse.

It takes way too much time to copy the unknown word into the clipboard, switch contexts, paste it in a translator and switch back.

What tool can I use to translate Spanish into English or German that offers an acceptable vocabulary?

Answer 1

There is Lingoes for on-screen translation with lots of free dictionaries:

It comes along with text capture plugins for Firefox, Chrome and Acrobat / Acrobat Reader.

HINT: You should run Lingoes as Administrator for the first time to be able to install the Acrobat plugin.

You can configure which action triggers the translation popup:
