A NEW Hot Key for Switch Tab without the Switch Tab Pop Up Window?

Everytime I hold CTRL + Tab, this window would show up below.







I would like to have a new hot key in which that window in that picture above would not show up.


For example, in the Firefox browser when I hold CTRL + Tab it would immediately switch to the next tab that is open. There wouldn't be any pop-up windows that would show up just like that image above.

Another feature that Firefox browser have is the Left switch tab and Right switch tab. If I hold CTRL + Page Up, it would immediately switch to the next tab, which is to the right direction and if I hold CTRL + Page Down, it would immediately switch to the previous tab, which is to the left direction.




Is there such feature that exist in in the Opera browser without that pop-up window that shows up? Yes, I'm referring to that pop-up window in the image that I uploaded in this post. I want that pop-up window to not show up when I'm rapidly switching tabs.

And I also would like to have the Opera Browser develop hotkeys for immediately switching tabs to the left direction and to the right direction just like the Left switch Tab and the Right switch Tab features that Firefox Browser is capable of without that pop-up window in that image that I uploaded above.

Ctrl+F6 takes you to the tab on the right
Ctrl+Shif+F6 takes you to the tab on the left

Preferences > Advanced > Tabs > Cycle without showing list [first drop down box]

Shortcuts 1, 2 also switch to previous/next page.

Thank you so much guys for your great help! Those are the shortcuts that I've been looking for!
