There is such a command exists already but it does not have a shortcut. I always assign Ctrl+Shift+T for it too.
Press Ctrl+Alt+S to go to settings and search for reopen clo...and assign a new shortcut to the command under Keymapsection.
Additionally this may come in handy too.
To open a recently opened file, choose View | Recent Files on the main
menu or press Ctrl+E. Then select the desired file from the Recent
Files pop-up window, that opens.
