Keyboard shortcuts take some getting used to, but offer a rewarding productivity boost for those willing to stick through the initial learning curve. Vimium is a Google Chrome extension that takes this mindset and runs with it, bolting a rich set of keyboard shortcuts on top of Chrome. Shortcuts are inspired by the Vim text editor, but can be remapped as needed. You can use Vimium to switch tabs, click links, select text boxes, and more, all without reaching for the mouse.
The two main features that make Vimium attractive are being able to quickly open links and advance to the next page in a paginated article using just the keyboard. If these are things you've always wanted to do, take Vimium for a spin--you may like its other features, too.
Note: The Download button takes you to the vendor's site, where you can install the latest version of the software directly into your Chrome browser.
