Perl regex trigger line:

\b(?:(?:(?:https?|ftp|telnet)://[\w\d:#@%/;$()~_?\+\-=&]+|www|ftp)(?:\.[\w\d:#@%/;$()~_?\+\-=&]+)+|[\w\d._%+\-]+@[\w\d.\-]+\.[\w]{2,4})\b

In the script box:

for i,v in ipairs(matches) do
  selectString(matches[i], 1)
  setLink([[openUrl("]]..matches[i]..[[")]], matches[i])
end

Set to match all.
