In a CMS, the right frame shows the page to be changed, and the left frame the editing page. I can double-click on a text-block in the right frame to open it in an editing area in the left frame. However, if I hit accidentally a link string, this opens the linked page (twice) additionally to copying the text into the edit area. I can prevent this behaviour in Firefox by keeping the alt key pressed while clicking on the link (in Linux and Windows).
What can I do in Safari/Mac to prevent opening links when clicking on them?
