If you use the Opera browser on your PC you'll probably be aware of the little shortcuts and mouse gestures the software uses to complete simple tasks.
Well it seems some of these shortcuts have been incorporated into the Wii version and the Wiimote.
Here's what's currently known:
Refresh: B+ D-pad up
Bookmarks: B+ D-pad down
Search: B+ D-pad left
Enter New Address: B+ D-pad right
Back: B+ (-)
Forward: B+ (+)
There might be some more hidden around too.
