Bug TC6.0: "Duplicate this tab" versus CTRL+T

[white]

Selecting "Duplicate this tab" from right click menu does not the same as it's shorcut CTRL+T
With CTRL+T the new tab has focus, but with rigth click menu it does not.

Apparently it's an error in the language file because if you use shift+ctrl+t it will create a duplicate tab and will not give the focus.
CTRL+T is equal to New folder tab.

Is it possible to make a clear difference to it.
- CTRL+T open a new tab at root level.
- SHIFT+CTRL+T make a duplicate.
