Only recently I became aware of the power of the Forward button on the Opera Web browser. It changes, depending on the content of the Web page.
Like other Web browsers, Opera can memorize passwords and usernames. When I go to a password-protected site, the Forward button changes to Login. Clicking Login fills in the data.
(When a site has more than one password, such as our family's banking site, then I still need to use the Wand button to select the password.)
On Web sites with collections of photos, such as the Photo Albums on my Typepad site, the Forward button changes to Next. Clicking Next displays the next photo.
This seems to also work (to a limited extent) on discussion groups: clicking Next displays the next message, usually.
Alternatively, I just press the spacebar to view the next photo. This has a catch however; if the Web page is larger than the screen, pressing spacebar scrolls the screen. Another press of the spacebar usually displays to the next photo.
When I get to the last photo, how do I get back to the first page? With Opera's Rewind button. It jumps back to the first link in a series, kind of like a super Back button.
