[[As for options, I am not sure if Chrome even enables Ctrl+Tab toggle btwn most recently opened tabs yet.]]
That’s what easystroke for linux is for (Yes, horrible name- cool app though) its a mouse gesture program- very handy, quick
I quickly toggle between open tabs using right mouse button press and diagonal up left, or right to go from tab to tab- right diagonal down to close a tab and ‘s’ (or whTEVER LETTER YOU ASSIGN) to close down computer, “C” Top open calculator- a ton of stuff you can do- once you get used to it ya don’t wanna live without it
Vivaldi has mouse gestures, but that is a poor substitute for not allowing Ctrl+Tab toggle btwn most recently opened tabs as an option which IIRC Chrome does not.
