How to become productive keyboard-only?

Question

I know the obvious shortcuts like Windows+[number] to open apps in the taskbar, CTRL+Arrows, SHIFT+Arrows. But I'd like to know how to become productive by using almost exclusively the keyboard. I'm talking about more advanced ones like pressing ' on Firefox lets me select links.Do you have any tips?
