How to open link in a new tab via shortcut in Chrome on Mac?
It will still take 30 clicks, one for each link, but…
Remember that  Cmd ⌘  on Mac is usually equivalent to  Ctrl ⌃  on Windows.
 Cmd ⌘  Click will open a link in a new a tab behind the current one, if you click a link.
 Cmd ⌘   Shift ⇧  Click will open the new tab &amp; bring it to the front.
These are the default settings [iirc] but they can be changed in Prefs…

Edit:
Sorry, I only just realised you said Chrome.
It does follow the same behaviour, though I can't find anywhere to actually change it.
