I have posted a similar message before, but the problem is clearer for me now. So I rephrase my question. When you search for a Chinese word, and the Chinese explanation pops up, it is possible to click on the Chinese characters in the popup screen and then get an explanation in English. I cannot do this in the PDF reader (popup screen). I then end up having to write the characters that I am reading on my Pleco PDF reader on my Samsung tablet again on my cell phone Pleco app to get the same explanation of the character, but the searchable version of the dictionary (not the PDF reader). Is it possible to implement this function in the popup screen in the PDF reader (make it a little more intuitive)?
