[twentythird]

Hi everyone. I saw l33t4opera's comment in Opera Blog about editing keybindings:
"Keybindings": {
"Basic": {
"PasteAndGo": [ "Ctrl+B" ]
},
"Settings": {
"AdvancedEnabled": false
}
}

And I think it's possible to edit mouse gestures same way. Does somebody know how I can do this?
Thanks.
