is there a function to switch to the last used, opened tab?

"previous tab" does mean the tab before in the row.
"last tab" does mean the last tab in the tab row?

there must be a jump back in tab-time :)

What means "next Tab", "previous Tab"?
Tab position or "tab history"?
Switch to the left/right tab or switch to the last watched tab?
Name it: "Swutch Tab right" or left :)
thx
