Topic: Used to be able to close current tab with 'command-w' (Mac) (being approved)

With multiple tabs, used to be able to close the current tab with 'command-w' (Mac). Now it closes the window (all tabs).

There appears to be no 'close tab' key combo: when I look in the 'File' item, 'Close Tab' is grayed out, and no key combo is displayed.

Can we please have a key combo to close the current tab (without closing all tabs)?
