Select the word and use the menu of right-mouse click.
Thanks Bernd for your reply.
However, I am looking for a mouse-over interactive function - instead of right click and select look up "word_definition", can Adobe show the word's definition when I move the mouse over the word? Do you think there is such plug-in?
When I use Adobe Reader “look up” function, it takes me to dictionary.com. I am wondering if Adobe Reader allows me to customize this look up function, so I can use another website or my offline dictionary, instead of going to dictionary.com.
Many thanks for your help/advice.
I am much more interested in not having to be directed to the internet at all for a dictionary. An plug-in that would either find a definition online, or use an offline dictionary to do so, and then present it to me without directing me to my web-browser would be fantastic.
I have this option available to me with both Microsoft Word, and on Google Chrome (makes reading on my computer MUCH easier, and less time-consuming). I would think that Adobe would also include this function since its competitors do as well.
