While our Mozilla Mail tutorial focuses on Windows, keep in mind that Mozilla Mail is a "cross-platform" email client: it runs and operates the same way on Windows, Apple's Mac OS X and Linux.
The Mozilla Foundation also offers the standalone Thunderbird email client: see the Mozilla Thunderbird Tutorial
Mozilla Mail Keyboard Shortcuts
This is a partial list of keyboard shortcuts for Mozilla Mail on Windows. We picked the ones you are most likely to use all the time. Keyboard shortcuts allow you to do quickly, without forcing your hands away from the keyboard, things you would naturally do with the mouse.
Keyboard Shortcuts Indicators on Menus
Whether you are using Windows, Macintosh, or UNIX, the menus of most applications actually reveal many keyboard shortcuts.
The screenshot on the left is Mozilla Mail's Message menu; notice the acronyms on the right of the menu items, they are keyboard shortcuts.
To reply to an email, for example, you can hold down the control key ("Ctrl") and press "R", (while still holding down the Ctrl key.)
To reply to all recipients of the email, hold down both Ctrl and Shift, and press "R"
