Hi all,
Recently I was browsing on interwebs and I fall in folling site: http://www.webupd8.org/2016/03/translate-any-text-you-select-on-your.html , in this site there an script to make translation but when triyng to test the script sadly I discover that not working anymore, but I don't care in start and with a library of python I tried to make a similar script with relative success, I know that my chances of success of my feature request was accept but I have to try.

so basically the script/feature could work this way when you select the text you trigger a combination of your keyboard and the selected text goes searched on the web and could appear an box with the meaning of selected text like the example of video[1].
So you could asking why develop this feature if already exist similar extensions for the translate unknow words of foreign languages like demonstrate in this another video[2], well this extension works only in browsers as I know at least, still not exist an feature to translate words of any application of your system like okular, libreoffice writer and so on, well my point is if this feature its add to the project students of another language will learn foreign languages with more easing without open a browser to translate unknow words.

Final thoughts:

off couse that I asking for this feature cause the developers od kde team can add more feature such select the destination language to translate the text or maybe add the meaning of the words and so on.
I hope that if my idea is not chosen this time at least this idea could be used in a close future, thanks for your time.
