There is a standard regarding tabs. Control+Tab switches between the last 2 open tabs. This is logical, that’s why its used. But of course some bonehead decided to flaunt convention and venture where no man has gone before!
At least consider fixing this. Its idiotic. Do you realize how irritating it is using software that ignore convention so my keyboard shortcuts have to be different when I’m using this browser? There’s a lot of competition out there that respects convention because its smarter to do that.
Or maybe its in the Setting somewhere, buried where few may find it. Surprise me!
