I do know that we can use Ctrl+Tab and Ctrl+Shift+Tab for opening next and previous tabs and also Ctrl+N for opening the Nth tab...
But what I am looking for is opening the previously opened tab (Qview in a remote).
Assume that I have 8 tabs open in a window, and I was previously on tab-3. Now I am on tab-7.
Now I need a key-combination that will take me back to tab-3. And once I move to tab-3 hitting the same key combination should bring me back to tab-7.
