Steps to reproduce the problem:
1. Open multiple tabs in a Chrome window
2. Press the following key combinations:
2.1 ⌘-⇧-→ 
2.2 ⌘-⇧-←
2.3 ⌘-Z

What is the expected behavior?
The following navigation should occur:
2.1 Select Next Tab
2.2 Select Previous Tab
2.3 Re-open Closed Tab

What went wrong?
On Mac, the the keyboard shortcuts listed above are system-defaults for tab navigation. These defaults can be observed in apps like Safari and Terminal. But Chrome's tab navigation shortcuts do not align.

Since function keys on Mac differ from other platforms and shortcuts for other navigation like “Close Tab” or “Preferences” are already platform-specific on Mac, it is expected that the shortcuts in question would also be mapped like Safari's on Mac.

Did this work before? No
