i have reduced my info as small as possible and used it as keyword . Is there any option of expanding the keyword if needed? like using external links which are clickable inside the palace over a particular keyword.

As of right now, there are no clickable keyword links. Do you mean that the keyword would link you to an outside webpage or that by clicking the keyword, you would just expand the text? What I would suggest is having the keyword and then in the referent section, adding all of the additional text. You could then keep the keywords always visible and view/hide the additional text by making the referent text visible or invisible.
