How to option-click on a browser link

I have built an AppleScript for this action, what is does:

  1. Gets a link from a KM variable.
    The target URL may be extracted from xpath using @JmichaelTX's script Copy the url address of the xPath

  2. Opens target URL in a new Safari tab, on the right after current active tab

  3. If KM variable with the target link is blank then a new tab won't be opened

The code:

tell application "Keyboard Maestro Engine"
   set myASVar to getvariable "Link"
   tell application "Safari"
      activate
      tell window 1 of application "Safari"
         get index of current tab
         set myActiveTab to current tab
         if myASVar is not "" then
            set myTab to make new tab at after myActiveTab with properties {URL:myASVar}
         end if
      end tell
   end tell
end tell
