When you use Word to deal with documents in the process of encountering the English words do not know, probably first thought of using an electronic dictionary, but unfortunately the computer is not installed. In fact, Word has a good document translation function, and in the latest word 2010, in addition to the previous document translation, choice of word translation and English assistant, but also added a "translation screen prompts" function, can be like an electronic dictionary to screen word translation.
Using Word 2010 to open a document with English, switch to the Review tab, click Translate, and then select Translate ScreenTip in the Drop-down menu.
Now just point the mouse at a word or a selected phrase, it will pop up a floating window to display the translation results, but at this time the window is translucent effect, it is difficult to see the above text. Small set guess this should be to avoid the mouse in the document will continue to pop-up translation window affect reading design, so want to see the word in the window, as long as the mouse moved to the floating window on it.
