Close Tab command

Currently closing a tab is set as [command + shift + W]
Can I close tab set as [command + W] ? Surely this should be the default.
I just checked that the current “Close Window” menu doesn’t have any command at all.
Is this a bug?

For some reason, I had to add in keyboard short cut for to Close window as [command+w] then it works for both tab and window closing in Totalfinder. Strange.
