The most difficult place to use shortcuts is in a web browser. But here the other day I discovered a neat tricks: When searching on google you can use the arrows and move down the list of results. A ctrl/cmd + enter click and the page opens in a new tab. The coolest thing is that with a right arrow click you get a preview of the page. Saves me some time and helps me to think more in breadth.
Scrolling is replaced by pageDown and PageUp. There are plugins to chrome and Firefox that adds letters to links so that you can open them with a shortcut combination. I find them to clutter up the web page too much.
