[ubuntu-za] Highlighting in a list

[SHAWN REITSTEIN]

Hi, how easy is it (if at all possible) to be able to highlight a line
in a list. Eg: in "Office", when one clicks "Open" - there's the list
of all saved Office documents...if one could highlight a line on the
list, it would be easier to find!? ( Bold, Cursive, underline - maybe
some different coloured highlights too? Is there such software? How
difficult to write? Also interested in a mouse- pen that can
write/draw anywhere, anytime on any page? Pls advise -
