Re: Make internal links in a wiki page open in a tab/window
For wiki pages, you can use the external link syntax for an internal link.
Internal link: ((HomePage))
External link: [http://domain.tld/HomePage|HomePage]
You must also have "Open external links in new window" selected in Admin Home -> Editing and Plugins, General Settings Tab, "External links and images" section.
Note: The link must be the full URL. Without the "http://domain.tld" prefix, [HomePage] works the same as an internal link and will not open the link in a new tab/window.
Full URLs for other options should open in a new tab/window when used with external link syntax also:
[forums] works as internal link
[http://domain.tld/forums|forums] works as external link
