This may be worth addressing to avoid regressing something available in Cocoa, but note that alt-enter offers the desired behavior (new foreground tab).

Oh yes, thanks.  ALT-ENTER works for me in MacViews. Never noticed that ALT-ENTER is working in Cocoa as well. 

Weird. This works for me on 70.0.3515.0. mehmet: Can you try to repro on latest canary?

Hi erikchen@,

I still can reproduce it with Canary Version 70.0.3515.0 on macOS 10.13.6 :-(

SHIFT-CMD-ENTER opens the tab in the background (like CMD-ENTER).

Maybe a Keyboard layout settings issue? I am using the Keyboard with the German layout settings.

Thank you for providing more feedback. Adding the requester to the cc list.

"but the new tab should be open in the foreground."

Ahh, missed that. Yeah, it opens in the background for me as well. I've confirmed that on Linux, alt + enter opens in foreground. This sounds like Views is explicitly using alt + enter on all platforms, even though it should use different behavior on macOS.

Should be an easy fix. Marking as Pri-1, M-70

[omnibox mac] Make command-shift-enter open tab in foreground

Currently the code falls through to "if (command) then open in
background." This change breaks out the variation if shift is
also pressed.

Able to reproduce the issue on chrome version 70.0.3511.0 (build without fix) as per the comment #0.
Verified the fix on Mac 10.13.5  using Chrome version # 70.0.3521.0 .
Attaching screen-cast for reference.
Observed that  " the new tab opened in the foreground " 
The fix is working as expected, adding Verified labels

Thanks...!!
