I think you are so right. He made a Evo 8 out of the fz5 (I saw it, and he did a great job). Also, I just found out Alt+R preveiws your message on here. And, it activates the printer menu. :doh:
My Logitech MX500 mouse's forward button/mouse gesture right (in Opera) also works as next page/or next something button (in default settings I might add no magic - just automagically chooses the next something). In LFS Forum it's the next newer thread than the current.
Good find, although I already knew that. I'd rather have it to go to the next thread page, I think it'd be more useful. It goes to "next page" in many websites, but some of them just go to "next newest" or "last page". I didn't try to configure it though, it might be possible to choose which action to perform.
That's because websites can be scripted to respond to Forward & Back browser buttons on the page itself instead of going forward and back in history. It's not the gestures, just the fact that the gestures control the browser's buttons.
