Press Space to scroll down a page and fast forward to the next one.
Whenever you’re browsing through content that’s been divided into pages (search results, online store catalog, etc.) you’ll likely do a lot of scrolling and looking for the “next page” button. In Vivaldi, you can do all of it with a single keyboard key.
By pressing Space, the page will be scrolled down a screen height at a time. Once you reach the end of the page, pressing Space will load the next page.
