Today it's all about navigation -- using your keyboard to work in and around your browser without reaching for the mouse. Learn to adopt these shortcuts and you'll enjoy a faster, more productive browsing experience.

These shortcuts work in all the major browsers: Chrome, Firefox, and Internet Explorer.

1. Move to the Next Tab or Last Tab

Like most users, I keep a lot of tabs open at the same time. Unlike most users, I don't grab my mouse whenever I want to switch between them.

Instead, I tap Ctrl-Tab to change focus to the next tab (i.e. the one to the right of the current one), and Ctrl-Shift-Tab for the previous tab (i.e. the one to the left). Try it, you'll like it.

2. Open a New Tab

Want to open a new tab in a flash? Just tap Ctrl-T. I find this especially useful when I've selected some text or a URL; I hit Ctrl-C to copy it, Ctrl-T to open a new tab, Ctrl-V to paste, and finally Enter to make it go.

That may sound like a lot of keystrokes, but they run together very quickly -- and they're way faster than clicking with the mouse.

3. Jump to the Top or Bottom of a Web Page

Borrowing from word processors, Web browsers use Home and End to jump to the top and bottom of a Web page. The only difference: no Ctrl key required.

Okay, those are my picks for the single most useful browser keyboard shortcuts ever. Now let's hear yours -- in the comments, of course.
