Add keyboard shortcuts to go faster without ever touching the mouse

[samuelroland]

In my personal opinion, it would be great to have some keyboard shortcuts for each action. I assume it is not easy to implement, to choose the appropriate keys combinations and to avoid overriding Firefox keyboard shortcuts...
Currently, I never did a keyboard shortcuts system before, and I don't know what are the Firefox constraints on it, so it's totally new for me and I need your comments !
As it's a big feature, thumb up the issue if it want to see it realized.
Feel free to share your opinion.
