Ha, that's an interesting take. My Dell work laptop has these (not full-sized) and I don't like them at all. There's nothing fun about trying to use the arrows and accidentally slipping onto a key that isn't usually there, which might scroll my cursor/window by a huge amount. My fingers expect no space there, so it makes the whole area less distinct to touch to have the spaces filled.

On my OS you can use CTRL+PgUp/PgDown to cycle through tabs, which makes the dedicated keys by the arrows really useful for single-handed tab cycling. Most other ways require a chord with both hands, so it’s just a lot slower.

Ctrl-tab can be pressed with one hand, no?

Ctrl-Tab serves a different function on my browser: go to last-used tab. Like Alt-Tab, but for browser tabs.

And Ctrl+shift+tab with the same exact hand to go the opposite direction.
