Just a quick tips on a chrome and Firefox plugin called Vimium. Ever wanted to browse without leaving the homerow? Avoid developing muscle issues cased by moving the mouse around, use keyboard shortcuts.
I am sure there are several other plugins that can provide you with shortcuts, and some of them are already built into the browser. One example is Ctrl-P for print.
However, what Vimium does is to map the VIM shortcuts to your browser. Shift-J is move tab to the left, Shift-K to the right. Shift-H is go back in the history and Shift-L is forward. Scrolling down and up is like doing it in VIM: J, K and d, u for page down/up.
