I started to use Opera, just because I've heard it was a good browser. While I don't think it's a bad browser, it will take time to get used to.
The main issue is that if you're comfortable with another browser (Firefox, Chrome, or IE) then it will be a hard progress to change, especially if you are used to your browser. I use FFox and Chrome, but there were a few keyboard-shortcuts that were significantly different in Opera.
The one I found most annoying was the shortcut to open a link in a new tab. In FF and Chrome, it's Ctrl + Left Click. This would open the link in a background tab. I know that middle-click works too, but I'm on a laptop touch-pad. The same control in Opera is Ctrl + Shift + Left Click. Ctrl + Left Click is the same as just a regular Left Click. Shift + Left Click opens the link in a new tab, but it's in the foreground.
My other frustration came shortly after this. Ctrl+Tab did not cycle through the tabs, but opened a menu of the tabs. Ctrl+Shift+Tab cycled through the menu backwards... similar, but different.
I really want to like Opera... It seems like it could be a good browser... has good features, but I also like my shortcuts. I think I would probably switch from Chrome to Opera if shortcuts were more compatible or customizable.
P.S. I also tried to change this in the preference menu, but nothing happened.
