Hi, I want a function Highlight(from_row, from_col, width, height, color) where from_row > 0 && from_col > 0 && width >=0 && height >=0 and zero means maximum. The highlight will stay until I call something to cancel it.
With this function, I can place a rule at column 80 with Highlight(1, 80, 1, 0, green), highlight all xml blocks like View Source Chart extension for Firefox (http://jennifermadden.com/scripts/ViewRenderedSource.html), make a table with colorized border and so on. I would greatly appreciate your help!
