GMail, or Google Mail, is a web-based email provider by Google.
Its key differentiators from other webmail services include an inbox based on conversations, labels instead of folders, and auto-saving for drafts.
It also has many keyboard shortcuts to make reading your email faster than ever.
To make it easier to visualize GMail's shortcut keys, I've grouped and color-coded them in correlation to Figure 1, below.
