Is it possible to select multiple tabs: the current tab and tabs to the left or right, using just the keyboard? (no mouse at all) - eviltoast

I’m trying to use my keyboard more since doing things with a mouse or trackpad is more time consuming. I’d like something like: pressing Control Shift Alt > to select the tab to the right (along with the current tab), and press it again to select the tab to the right of that, making it three tabs selected. Same thing with tabs to the left.
