How to make urxvt open link when clicked with Ctrl

Currently urxvt recognizes links and underlines them. While clicked, it opens them in firefox. Here's my current .Xresources: URxvt.perl-ext: default,matcher URxvt.url-launcher: firefox URxvt.matcher.button: 1 URxvt.matcher.pattern.1: \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-] I want urxvt not to underline links by default. I want it to underline them only when mouse is over them. I also want urxvt to do nothing when their are clicked, but to open them when their are clicked with Ctrl key.
